Subject: cx18: Fix write retries for registers that always change - part 2.

From: Andy Walls <awalls@radix.net>

cx18: Fix write retries for registers that always change - part 2.
Some registers, especially interrupt related ones, will never read
back the value just written.  Modified interrupt register readback
checks to make sure the intended effect was achieved.

Priority: high

Subject: cx18: Mark CX18_CPU_DE_RELEASE_MDL as a slow API call

From: Andy Walls <awalls@radix.net>

cx18: Mark CX18_CPU_DE_RELEASE_MDL as a slow API call.
Give the encoder time to complete the MDL release before destroying the
encoder internal task.  This avoids an encoder lockup on the next digital
capture and error messages about buffers being returned for an inactive
encoder task handle.

From: Andy Walls <awalls@radix.net>

cx18: Fix write retries for registers that always change - part 3.
Fix the io for the rest of the registers that will often not read back the
value just written.  Modified register readback checks to make sure the
intended effect was achieved without constantly rewriting the registers.
The one outstanding register remaining is 0xc72014 CX18_AUDIO_ENABLE, whose
behavior on writes I have yet to determine.

Subject: cx18: Reduce number of mmio read retries

From: Andy Walls <awalls@radix.net>

cx18: Reduce number of mmio read retries to improve performance.  Experiments
have shown 2 things: read retries never improve the result of a suspect mmio
read from the CX23418 (the result stays all 0xff's), and that most of the
suspected read failures are actually proper reads of values that should be
all 0xff's.  This change reduces the number of read retries and keeps the
count separate from write retries.

Priority: normal

Subject: cx18: Fix PLL freq computation for debug display

From: Andy Walls <awalls@radix.net>

cx18: Fix PLL freq computation for debug display.
The code to compute the PLL freq from register values was storing an
intermediate 56 bit result in a 32 bit type, causing a nonsense value to
be displayed.

 cleanup

From: Andy Walls <awalls@radix.net>

cx18: Use correct Mailbox IRQ Ack values and misc IRQ handling cleanup.
The SCB field definitions for Ack IRQ's for mailboxes were inconsistent with
the bitmasks being loaded into those SCB fields and the SW2 Ack IRQ handling
logic.  Renamed fields in SCB to make things consistent and did misc IRQ
handling cleanups: removing legacy ivtv dma_reg_lock, HPU IRQ flags, etc.

Subject: cx18: Move DVB buffer transfer handling from irq handler to
 work_queue

From: Andy Walls <awalls@radix.net>

cx18: Move DVB buffer transfer handling from irq handler to work_queue thread.
In order to properly lock the epu2cpu mailbox for driver to CX23418 commands,
the DVB/TS buffer handling needs to be moved from the IRQ handler and IRQ
context to a work queue.  This work_queue implmentation is strikingly similar
to the ivtv implementation - for better or worse.

Priority: high

Subject: cx18: Use default kernel work queue; fix streaming flag for work
 handler

From: Andy Walls <awalls@radix.net>

cx18: Use default kernel work queue; fix streaming flag for work handler.
Eliminate cx18 specific work queue and use the kernel default work queue.
Fixed the F_STREAMING_FLAG for the TS stream so cx18_dvb_work_handler()
can know when it is not safe to send MDLs to the firmware.

Priority: high

Subject: cx18: Add outgoing mailbox mutexes and check for ack via waitq vs
 poll

From: Andy Walls <awalls@radix.net>

Add mutexes to ensure exclusive access for outgoing driver to CX23418 mailboxes.
Also wait on a waitq for mailbox acknowledgement from the CX23418 instead of
polling.

Priority: high

Subject: cx18: Improve handling of outgoing mailboxes detected to be busy

From: Andy Walls <awalls@radix.net>

cx18: Improve handling of outgoing mailboxes detected to be busy.  When
encountering a busy mailbox, sleep instead of polling, and wait for interrupt or
timeout.  If the mailbox is still busy, force it free.  When sending commands,
make sure we never create a situation where we mark the mailbox busy upon
sending, and ensure we always have a method to cleanly recover from a busy
mailbox.

Priority: high

Subject: dsbr100: add suspend and resume

From: Alexey Klimov <klimov.linux@gmail.com>

This patch adds support for suspend and resume methods in driver.
Without this kradio and gnomeradio crashes during resume.
Also .supports_autosuspend in usb_driver struct set equal to 0 to avoid
suspending of module if usb_autosuspend enabled.

 performnce

From: Andy Walls <awalls@radix.net>

All waits for cx18 mailbox API commands are now uninterruptable.  Added
code to collect mailbox ack statistics.  Tweaked timeouts based on collected
stats and video vertical frame and field rates.

Priority: normal

Subject: cx18: Minor fixes to APU firmware load process

From: Andy Walls <awalls@radix.net>

Use the APU fw start address from rom file instead of a hardcoded entry vector.
Fixed cx18_setup_page() calls to use the correct APU image load addresses.

Priority: normal

Subject: uvcvideo: Sort the frame descriptors during parsing

From: Laurent Pinchart <laurent.pinchart@skynet.be>

The UVC specification does not require frame descriptors to be sorted by
bFrameIndex. At least one camera (145f:013e) is known not to sort the
descriptors properly, so they need to be sorted during parsing as the driver
then accesses them by index.

Subject: uvcvideo: Handle failed video GET_{MIN|MAX|DEF} requests more
 gracefully

From: Laurent Pinchart <laurent.pinchart@skynet.be>

Failed requests will now generate a one-time warning message instead of the
usual "Failed to query..." error, which should be more user-friendly. The
driver will also recover automatically from failed GET_MIN/GET_MAX requests
when the device is half-broken without requiring the MINMAX quirk (fully
broken devices still need the quirk).

Subject: cx18: Prevent CX23418 from clearing it's outgoing ack interrupts to
 driver

From: Andy Walls <awalls@radix.net>

When the CX23418 CPU unit sent out an ack interrupt to the linux driver, it
also received that interrupt and cleared the flag before the linux driver could
see what the interrupt was for.  This fix prevents the CPU from receiving an
IRQ for it's own outgoing ack's to the linux driver.  This fix is critical now
that the linux driver doesn't poll but relies on these ack interrupts.

Priority: high

Subject: cx18: Fix unitialized variable problem upon APU firmware file read
 failure

From: Andy Walls <awalls@radix.net>

If APU firmware file read failed, the jump vector to the APU was undefined and
the APU would be started executing garbage.  Fix uninitialized variable to be
an infinite loop for the APU, but also bail out before even starting the APU.

Subject: uvcvideo: Enable compilation on kernels older than 2.6.22

From: Laurent Pinchart <laurent.pinchart@skynet.be>

The uvcvideo driver makes use of the usb_endpoint_* functions as well as
the list_first_entry and uninitialized_var macros. Add them to v4l/compat.h
and update the driver with kernel version-based conditional compilation
sections.

Subject: v4l core: add support for enumerating frame sizes and intervals

From: Mauro Carvalho Chehab <mchehab@redhat.com>

video_ioctl2 lacks implementation of those two ioctls:
	- VIDIOC_ENUM_FRAMESIZES and VIDIOC_ENUM_FRAMEINTERVALS

Adds implementation for those.

Priority: normal

Subject: Remember chip id of devices at initialization

From: Devin Heitmueller <devin.heitmueller@gmail.com>

Remember chip id of devices at initialization


When setting up the device, remember the chip id, so we can control behavior
in the future without having to read the register continuously.

Subject: Support different GPIO/GPO registers for newer devices

From: Devin Heitmueller <devin.heitmueller@gmail.com>

Support different GPIO/GPO registers for newer devices


Empia moved the location of the GPIO/GPO registers in newer devices.  Add the
ability to specify the relocated registers (including caching of register
contents).

Thanks for Ray Lu from Empia for providing the em2874 datasheet.

Subject: Skip reading eeprom in newer Empia devices

From: Devin Heitmueller <devin.heitmueller@gmail.com>

Skip reading eeprom in newer Empia devices


Empia switched to a 16-bit addressable eeprom in newer devices.  While we
could certainly write a routine to read the eeprom, there is nothing of use
in there that cannot be accessed through registers, and there is the risk that
we could corrupt the eeprom (since a 16-bit read call is interpreted as a
write call by 8-bit eeproms).  So just be safe and bail out of the function.

Thanks for Ray Lu from Empia for providing the em2874 datasheet.

Subject: Properly support capture start on em2874

From: Devin Heitmueller <devin.heitmueller@gmail.com>

Properly support capture start on em2874


The transport stream enable register moved in the em2874, so make it work
properly.

Thanks for Ray Lu from Empia for providing the em2874 datasheet.

Subject: em28xx: Properly implement poll support for IR's

From: Mauro Carvalho Chehab <mchehab@redhat.com>

The first em28xx were based on i2c IR's. However, some newer designs
are coming with a polling-based IR. Those are done by reading a register
set at em28xx.

This patch adds core polling support for those devices. Later patches will
add support for some device-specific IR's.

This patch adds the same basic IR polling code used by bttv, cx88 and saa7134, and
shares the common getkey masks defined at ir-common.

Subject: uvcvideo: Commit streaming parameters when enabling the video stream.

From: Laurent Pinchart <laurent.pinchart@skynet.be>

Sonix-based cameras seem to require the host to commit video streaming
parameters before selecting the alternate endpoint. While most applications
issue a VIDIOC_S_FMT ioctl before starting streaming, this is not required
by the V4L2 specification.

The problem has been noticed on Ubuntu 8.10 with applications using libv4l.
The library blocks VIDIOC_S_FMT calls when the requested format is identical
to the currently selected format. As the driver commits video streaming
parameters when initialising the device, only the first run of a
libv4l-enabled application would succeed.

For the sake of completeness, experiment showed that the camera keeps sending
12 bytes isochronous packets (header only, no data) without toggling the FID
bit if video streaming parameters haven't been committed before selecting the
alternate endpoint.

Priority: normal

From: Devin Heitmueller <devin.heitmueller@gmail.com>

Refactor the em28xx IR support based on the em2860/em2880 and em2874
datasheets.

Tested on the HVR-950 (em2883), Pinnacle 800e (em2883), Pinnacle 80e (em2874)
using the remote controls that came with those products.

Subject: Put s5h1411 into low power mode at end of attach() call

From: Devin Heitmueller <devin.heitmueller@gmail.com>

Place the s5h1411 into low power mode until first use (to handle the case where
the user plugs in the device and then doesn't use it for a while).  On the
Pinnacle 801e, this brings the power usage from 126ma down to 82ma.

Subject: Make sure the i2c gate is open before powering down tuner

From: Devin Heitmueller <devin.heitmueller@gmail.com>

It is not safe to assume that the i2c gate will be open before issuing the
command to power down the tuner.  In fact, many demods only open the gate
long enough to issue the tuning command.

This fix allows power management to work properly for those tuners behind an
i2c gate (in my case the problem was with the HVR-950Q)

ARRAY_SIZE is more concise to use when the size of an array is divided by
the size of its type or the size of its first element.

Subject: tvaudio: instead of using a magic number, use ARRAY_SIZE

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Also, the default standard is the first one. So, fix the comment at the
array.

Subject: tvtime: avoid OOPS at generic_checkmode()

From: Mauro Carvalho Chehab <mchehab@redhat.com>

generic_checkmode() were called, via a callback, for some tvaudio chips.
There's just one callback code used on all those boards. So, it makes no
sense on keeping this as a callback.

Since there were some OOPS reported on tvaudio on kerneloops.org, this
patch removes this callback, adding the code at the only place were it
is called: inside chip_tread. A flag were added to indicate the need for
a kernel thread to set stereo mode on cards that needs it.

Priority: high

Subject: tvaudio: add additional logic to avoid OOPS

From: Mauro Carvalho Chehab <mchehab@redhat.com>

This patch checks for volume, bass, treble, set mode and get mode
callbacks before actually enabling the code that would use them.

Instead of aborting the driver for load, this patch will allow it to
load with a reduced number of functionatities.

This prevents OOPS if some board entry is missing a needed callback.

Priority: high

Subject: tvaudio: update initial comments

From: Mauro Carvalho Chehab <mchehab@redhat.com>

A driver used on several bttv boards since 2000 is not experimental
anymore ;) Remove it from the comments.

While there, update copyrights addind a quick note about the "recent"
updates since 2005.

Subject: af9015: don't reconnect device in USB-bus

From: Jose Alberto Reguero <jareguero@telefonica.net>

Don't reconnect device in the USB-bus. Reconnect command was not executed every time by device firmware and that causes harm. Reconnection is not needed so remove it.

Subject: tvaudio: use a direct reference for chip description

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Instead of storing the pointer for the proper entry at chip description
table, the driver were storing an indirect reference, by using an index.
Better to reference directly the data.

Adds support for the Digittrade DVB-T USB Stick remote.
As the Digittrade USB stick identifies itself as a generic Afatech AF9015
device, the remote cannot be autodetected. To enable it, add the following
to /etc/modprobe.d/dvb-usb-af9015 or /etc/modprobe.conf:

Subject: uvcvideo: Fix printk badness when printing ioctl names

From: Laurent Pinchart <laurent.pinchart@skynet.be>

Add a trailing newline character after calling v4l_printk_ioctl() to avoid
messing the kernel log up and merge the uvc_v4l2_ioctl message with the ioctl
name.

Priority: normal

Subject: radio-mr800: fix unplug

From: Alexey Klimov <klimov.linux@gmail.com>

This patch fixes problems(kernel oopses) with unplug of device while
it's working.
Patch adds disconnect_lock mutex, changes usb_amradio_close and
usb_amradio_disconnect functions and adds a lot of safety checks.

Subject: Avoid having two concurrent control URB's

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Now that we have a polling task for IR, there's a race condition, since
IR can be polling while other operations are being doing. Also, we are
now sharing the same urb_buf for both read and write control urb
operations. So, we need a mutex.

Thanks to Davin Heitmueller <devin.heitmueller@gmail.com> for warning me.

Subject: em28xx: Improve audio handling

From: Mauro Carvalho Chehab <mchehab@redhat.com>

This patch properly implements audio handling on em28xx. Before this
patch, it was assumed that every device has an Empia 202 audio chip.
However, this is not true.

After this patch, specific AC97 chipset setup and configurations can be
done.

Priority: normal

Subject: em28xx: merge AC97 vendor id's into a single var

From: Mauro Carvalho Chehab <mchehab@redhat.com>

This makes easier to identify vendor ID, since AC97 vendors are
generally identified by 3 bytes. The remaining byte is used by the
vendor to identify its devices.

Priority: normal

Subject: em28xx: improve AC97 handling

From: Mauro Carvalho Chehab <mchehab@redhat.com>

AC97 devices provide several input and outputs. However, before this
patch, em28xx device weren't properly allowing the usage of ac97
possible combinations. Also, several input volumes were left untouched,
instead of making sure that the volumes were set on mute state.

This patch improves support for ac97 devices by allowing to use any
inputs, and making sure that unused inputs are set on mute state.

Yet, some work is still needed to select the AC97 output.

Priority: normal

Subject: tvaudio: fix OOPS when controlling bass/treble

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Not all tvaudio chips allow controlling bass/treble. So, the driver
has a table with a flag to indicate if the chip does support it.

Unfortunately, the handling of this logic were broken for a very long
time (probably since the first module version). Due to that, an OOPS
were generated for devices that don't support bass/treble.

This were the resulting OOPS message before the patch, with debug messages
enabled:

Subject: Make dib0700 remote control support work with firmware v1.20

From: Devin Heitmueller <devin.heitmueller@gmail.com>

The format for reading the IR controller changed in firmware 1.20.  It now
provides the events on bulk endpoint 1 instead of using a control request.

Support the new format, providing backward compatibility for users who might
be using older firmware.

Thanks to Patrick Boettcher <patrick.boettcher@desy.de> for providing the
required information on how the version 1.20 firmware works.

Priority: high

Subject: cx18: Major rewrite of interrupt handling for incoming mailbox
 processing

From: Andy Walls <awalls@radix.net>

A major rewrite of interrupt handling for incoming mailbox processing, to split
the timing critical steps from the the deferrable steps as the sending XPU on
the CX23418 will time out and overwrite our incoming mailboxes rather quickly.
Setup a pool of work "order forms" for the irq handler to send jobs to the new
work handler routine which uses the kernel default work queue to do the
deferrable work.  Started optimizing some of the cx18-io calls as they are now
the low hanging fruit for recoving microseconds back from the timeline.
Future optimizations will get rid of mmio read retries, mmio stats logging, and
combine smaller functions in the irq path into the larger ones to save ~2 us
each.

Priority: normal

Subject: cx18: Change to singlethreaded global work queue thread for deferable
 work

From: Andy Walls <awalls@radix.net>

Change to singlethreaded global work queue thread for deferable work,
instead of the kernel default multithreaded work queue.  This ensures
execution of deferable work is always in the proper order, so caputred buffers
don't get reordered.

Subject: cx18: Convert per stream queue spinlocks into mutexes

From: Andy Walls <awalls@radix.net>

Convert the per stream queue spinlocks into mutexes.  All queue
manipulation happens via the work queue or system calls into the driver, and
not in an interrupt context.  This reduces the amout of time the cx18 driver
keeps interrupts disabled.

Priority: normal

Subject: cx18: Propagate staleness of mailbox and mdl ack data to work handler

From: Andy Walls <awalls@radix.net>

cx18: Propagate staleness of mailbox and mdl ack data to work handler to let
the work handler know that the data from the encoder may not be coherent.
Allows for smarter handling of buffers in future, to deal with MDLs that fall
out of rotation due to irq handler being late in collecting mailbox and mdl ack
info.

Subject: cx18: Streamline cx18-io[ch] wrappers and enforce MMIO retry strategy

From: Andy Walls <awalls@radix.net>

cx18: Streamline cx18-io[ch] wrappers and enforce MMIO retry strategy so that
write retries always occur and read retries never occur (as they never help).
Remove MMIO statistics logging to speed up MMIO accesses.  Deprecate & ignore
retry_mmio and mmio_ndelay module parameters, to essentially force
retry_mmio=1 and mmio_ndelay=0.

Subject: gspca: Correct restart of webcams in spca501.

From: Hans de Goede <hdegoede@redhat.com>

Currently the spca501 driver only works the first time used, then the cam needs
to be unplugged or the driver reloaded, this is because currently the data
which should be send each time the stream is started is send only once.
Likewise currently the data to initialize the cam is send from the probe
function, and thus will not get send after a suspend/resume.
This patch fixes this by sending both at the right time.

Priority: normal

Subject: gspca: Don't return the control values from the webcams in spca501.

From: Hans de Goede <hdegoede@redhat.com>

The bridge takes some time to update after a write, so apps doing a quick
write/read can get the old value back.

Subject: Remove the previous register names

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Previously, AC97 registers were named as if they were part of em28xx
device, generating some confusion. Replace such names for a more general
naming convention.

Subject: cx18: Remove unnecessary MMIO accesses in time critical irq handling
 path

From: Andy Walls <awalls@radix.net>

Remove unnecessary MMIO accesses in time critical irq handling path.  Also
ensured that the mailbox ack field is read in last, so we know for sure if we
have a stale mailbox or not on receipt.

This permits the subdriver to free its resources.

Priority: high

Subject: em28xx: Avoid memory leaks if registration fails

From: Mauro Carvalho Chehab <mchehab@redhat.com>

em28xx_init_dev() has some error conditions that are not properly
de-allocating dev var, nor freeing the device number for a future usage.

Subject: em28xx: avoid allocating/dealocating memory on every control urb

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Before this patch, every register setup on em28xx were dynamically
allocating a temporary buffer for control URB's to be handled.

To avoid this ping-pong, use, instead a pre-allocated buffer.

Also, be sure that read control URB's also use the buffer, instead of
relying on a stack buffer.

Subject: gspca: Lock the subdrivers via module_get/put.

From: Jean-Francois Moine <moinejf@free.fr>

The previous subdriver protection against rmmod was done via the
file operations table in the device descriptor. On device disconnection
while streaming, the device structure was freed at close time, and the
module_put still used the module name in the freed area.
Now, explicit module get/put are done on open and close.

Subject: gspca: Move the video device to a separate area.

From: Jean-Francois Moine <moinejf@free.fr>

The video device was part of the gspca device. On device disconnection
while streaming, the device structure is freed at close time.
In this case, the remaining close job on the video device run out of
allocated memory.

Priority: high

Subject: em28xx: fix a race condition with hald

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Newer versions of hald tries to open it to call QUERYCAP.

Due to the lack of a proper locking, it is possible to open the device
before it finishes initialization.

This patch adds a lock to avoid this risk, and to protect the list of
em28xx devices.

While here, remove the uneeded BKL lock.

Priority: high

Subject: em28xx: allow specifying audio output

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Some boards use different AC97 setups for output. This patch adds the
capability of specifying the output to be used. Currently, only one

Subject: em28xx: fix Pixelview PlayTV board entry

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Pixelview uses a Sigmatel stac codec. It has an external line out pin,
connected to AC97_MASTER_VOL. It also provides I2S output, but using a
different volume for this (AC97_MONO_VOL).

Now that AC97 setup is finally fixed, such boards will work better.

Subject: af9015: fix compilation error

From: Hans Verkuil <hverkuil@xs4all.nl>

It is much more readable to swap the byteorder in the switch rather
than in each case statement. In addition, this fixes a compile error
when compiled for 2.6.16.

Subject: cx18: Adjust outgoing mailbox timeouts and remove statistics logging

From: Andy Walls <awalls@radix.net>

cx18: Adjust outgoing mailbox timeouts and remove statistics logging.
This saves some wasted storage in struct cx18 for each card.  Cutting
the outgoing mailbox timeouts in half from the previous value appears to
be safe with MythTV.  Got rid of interrupted case code path after
a wait uninterruptable returns.

Priority: normal

Subject: gspca:Subdriver ov534 added.

From: Antonio Ospite <ospite@studenti.unina.it>

The OmniVision OV534 is the USB bridge chip used in Sony Playstation EYE,
it is found also in other webcams like Hercules Blog Webcam and
Hercules Dualpix HD.
This driver is the port to gspca of a prototype driver by Mark Ferrell
based on vivi. The original code to initialize the camera and start the
capture is from Jim Paris on ps2dev.org, here integrated with the analysis
of the USB communications taken by the windows driver.

Subject: gspca: Fix an access to freed memory at disconnect time.

From: leandro Costantino <lcostantino@gmail.com>

On disconnection (USB or rmmod subdriver), the device is freed
by video_unregister_device(). Setting the 'present' and 'streaming'
flags must be done before the call to this function.

Subject: em28xx: improve message probing logs

From: Mauro Carvalho Chehab <mchehab@redhat.com>

On some em28xx devices, there's an unused interface. This is printed on
the logs as an error. We can just ignore that interface.

+Overview of the V4L2 driver framework
+=====================================
+
+This text documents the various structures provided by the V4L2 framework and
+their relationships.
+
+
+Introduction
+------------
+
+The V4L2 drivers tend to be very complex due to the complexity of the
+hardware: most devices have multiple ICs, export multiple device nodes in
+/dev, and create also non-V4L2 devices such as DVB, ALSA, FB, I2C and input
+(IR) devices.
+
+Especially the fact that V4L2 drivers have to setup supporting ICs to
+do audio/video muxing/encoding/decoding makes it more complex than most.
+Usually these ICs are connected to the main bridge driver through one or
+more I2C busses, but other busses can also be used. Such devices are
+called 'sub-devices'.
+
+For a long time the framework was limited to the video_device struct for
+creating V4L device nodes and video_buf for handling the video buffers
+(note that this document does not discuss the video_buf framework).
+
+This meant that all drivers had to do the setup of device instances and
+connecting to sub-devices themselves. Some of this is quite complicated
+to do right and many drivers never did do it correctly.
+
+There is also a lot of common code that could never be refactored due to
+the lack of a framework.
+
+So this framework sets up the basic building blocks that all drivers
+need and this same framework should make it much easier to refactor
+common code into utility functions shared by all drivers.
+
+
+Structure of a driver
+---------------------
+
+All drivers have the following structure:
+
+1) A struct for each device instance containing the device state.
+
+2) A way of initializing and commanding sub-devices (if any).
+
+3) Creating V4L2 device nodes (/dev/videoX, /dev/vbiX, /dev/radioX and
+   /dev/vtxX) and keeping track of device-node specific data.
+
+4) Filehandle-specific structs containing per-filehandle data.
+
+This is a rough schematic of how it all relates:
+
+    device instances
+      |
+      +-sub-device instances
+      |
+      \-V4L2 device nodes
+	  |
+	  \-filehandle instances
+
+
+Structure of the framework
+--------------------------
+
+The framework closely resembles the driver structure: it has a v4l2_device
+struct for the device instance data, a v4l2_subdev struct to refer to
+sub-device instances, the video_device struct stores V4L2 device node data
+and in the future a v4l2_fh struct will keep track of filehandle instances
+(this is not yet implemented).
+
+
+struct v4l2_device
+------------------
+
+Each device instance is represented by a struct v4l2_device (v4l2-device.h).
+Very simple devices can just allocate this struct, but most of the time you
+would embed this struct inside a larger struct.
+
+You must register the device instance:
+
+	v4l2_device_register(struct device *dev, struct v4l2_device *v4l2_dev);
+
+Registration will initialize the v4l2_device struct and link dev->driver_data
+to v4l2_dev. Registration will also set v4l2_dev->name to a value derived from
+dev (driver name followed by the bus_id, to be precise). You may change the
+name after registration if you want.
+
+You unregister with:
+
+	v4l2_device_unregister(struct v4l2_device *v4l2_dev);
+
+Unregistering will also automatically unregister all subdevs from the device.
+
+Sometimes you need to iterate over all devices registered by a specific
+driver. This is usually the case if multiple device drivers use the same
+hardware. E.g. the ivtvfb driver is a framebuffer driver that uses the ivtv
+hardware. The same is true for alsa drivers for example.
+
+You can iterate over all registered devices as follows:
+
+static int callback(struct device *dev, void *p)
+{
+	struct v4l2_device *v4l2_dev = dev_get_drvdata(dev);
+
+	/* test if this device was inited */
+	if (v4l2_dev == NULL)
+		return 0;
+	...
+	return 0;
+}
+
+int iterate(void *p)
+{
+	struct device_driver *drv;
+	int err;
+
+	/* Find driver 'ivtv' on the PCI bus.
+	   pci_bus_type is a global. For USB busses use usb_bus_type. */
+	drv = driver_find("ivtv", &pci_bus_type);
+	/* iterate over all ivtv device instances */
+	err = driver_for_each_device(drv, NULL, p, callback);
+	put_driver(drv);
+	return err;
+}
+
+Sometimes you need to keep a running counter of the device instance. This is
+commonly used to map a device instance to an index of a module option array.
+
+The recommended approach is as follows:
+
+static atomic_t drv_instance = ATOMIC_INIT(0);
+
+static int __devinit drv_probe(struct pci_dev *dev,
+				const struct pci_device_id *pci_id)
+{
+	...
+	state->instance = atomic_inc_return(&drv_instance) - 1;
+}
+
+
+struct v4l2_subdev
+------------------
+
+Many drivers need to communicate with sub-devices. These devices can do all
+sort of tasks, but most commonly they handle audio and/or video muxing,
+encoding or decoding. For webcams common sub-devices are sensors and camera
+controllers.
+
+Usually these are I2C devices, but not necessarily. In order to provide the
+driver with a consistent interface to these sub-devices the v4l2_subdev struct
+(v4l2-subdev.h) was created.
+
+Each sub-device driver must have a v4l2_subdev struct. This struct can be
+stand-alone for simple sub-devices or it might be embedded in a larger struct
+if more state information needs to be stored. Usually there is a low-level
+device struct (e.g. i2c_client) that contains the device data as setup
+by the kernel. It is recommended to store that pointer in the private
+data of v4l2_subdev using v4l2_set_subdevdata(). That makes it easy to go
+from a v4l2_subdev to the actual low-level bus-specific device data.
+
+You also need a way to go from the low-level struct to v4l2_subdev. For the
+common i2c_client struct the i2c_set_clientdata() call is used to store a
+v4l2_subdev pointer, for other busses you may have to use other methods.
+
+From the bridge driver perspective you load the sub-device module and somehow
+obtain the v4l2_subdev pointer. For i2c devices this is easy: you call
+i2c_get_clientdata(). For other busses something similar needs to be done.
+Helper functions exists for sub-devices on an I2C bus that do most of this
+tricky work for you.
+
+Each v4l2_subdev contains function pointers that sub-device drivers can
+implement (or leave NULL if it is not applicable). Since sub-devices can do
+so many different things and you do not want to end up with a huge ops struct
+of which only a handful of ops are commonly implemented, the function pointers
+are sorted according to category and each category has its own ops struct.
+
+The top-level ops struct contains pointers to the category ops structs, which
+may be NULL if the subdev driver does not support anything from that category.
+
+It looks like this:
+
+struct v4l2_subdev_core_ops {
+	int (*g_chip_ident)(struct v4l2_subdev *sd, struct v4l2_chip_ident *chip);
+	int (*log_status)(struct v4l2_subdev *sd);
+	int (*init)(struct v4l2_subdev *sd, u32 val);
+	...
+};
+
+struct v4l2_subdev_tuner_ops {
+	...
+};
+
+struct v4l2_subdev_audio_ops {
+	...
+};
+
+struct v4l2_subdev_video_ops {
+	...
+};
+
+struct v4l2_subdev_ops {
+	const struct v4l2_subdev_core_ops  *core;
+	const struct v4l2_subdev_tuner_ops *tuner;
+	const struct v4l2_subdev_audio_ops *audio;
+	const struct v4l2_subdev_video_ops *video;
+};
+
+The core ops are common to all subdevs, the other categories are implemented
+depending on the sub-device. E.g. a video device is unlikely to support the
+audio ops and vice versa.
+
+This setup limits the number of function pointers while still making it easy
+to add new ops and categories.
+
+A sub-device driver initializes the v4l2_subdev struct using:
+
+	v4l2_subdev_init(subdev, &ops);
+
+Afterwards you need to initialize subdev->name with a unique name and set the
+module owner. This is done for you if you use the i2c helper functions.
+
+A device (bridge) driver needs to register the v4l2_subdev with the
+v4l2_device:
+
+	int err = v4l2_device_register_subdev(device, subdev);
+
+This can fail if the subdev module disappeared before it could be registered.
+After this function was called successfully the subdev->dev field points to
+the v4l2_device.
+
+You can unregister a sub-device using:
+
+	v4l2_device_unregister_subdev(subdev);
+
+Afterwards the subdev module can be unloaded and subdev->dev == NULL.
+
+You can call an ops function either directly:
+
+	err = subdev->ops->core->g_chip_ident(subdev, &chip);
+
+but it is better and easier to use this macro:
+
+	err = v4l2_subdev_call(subdev, core, g_chip_ident, &chip);
+
+The macro will to the right NULL pointer checks and returns -ENODEV if subdev
+is NULL, -ENOIOCTLCMD if either subdev->core or subdev->core->g_chip_ident is
+NULL, or the actual result of the subdev->ops->core->g_chip_ident ops.
+
+It is also possible to call all or a subset of the sub-devices:
+
+	v4l2_device_call_all(dev, 0, core, g_chip_ident, &chip);
+
+Any subdev that does not support this ops is skipped and error results are
+ignored. If you want to check for errors use this:
+
+	err = v4l2_device_call_until_err(dev, 0, core, g_chip_ident, &chip);
+
+Any error except -ENOIOCTLCMD will exit the loop with that error. If no
+errors (except -ENOIOCTLCMD) occured, then 0 is returned.
+
+The second argument to both calls is a group ID. If 0, then all subdevs are
+called. If non-zero, then only those whose group ID match that value will
+be called. Before a bridge driver registers a subdev it can set subdev->grp_id
+to whatever value it wants (it's 0 by default). This value is owned by the
+bridge driver and the sub-device driver will never modify or use it.
+
+The group ID gives the bridge driver more control how callbacks are called.
+For example, there may be multiple audio chips on a board, each capable of
+changing the volume. But usually only one will actually be used when the
+user want to change the volume. You can set the group ID for that subdev to
+e.g. AUDIO_CONTROLLER and specify that as the group ID value when calling
+v4l2_device_call_all(). That ensures that it will only go to the subdev
+that needs it.
+
+The advantage of using v4l2_subdev is that it is a generic struct and does
+not contain any knowledge about the underlying hardware. So a driver might
+contain several subdevs that use an I2C bus, but also a subdev that is
+controlled through GPIO pins. This distinction is only relevant when setting
+up the device, but once the subdev is registered it is completely transparent.
+
+
+I2C sub-device drivers
+----------------------
+
+Since these drivers are so common, special helper functions are available to
+ease the use of these drivers (v4l2-common.h).
+
+The recommended method of adding v4l2_subdev support to an I2C driver is to
+embed the v4l2_subdev struct into the state struct that is created for each
+I2C device instance. Very simple devices have no state struct and in that case
+you can just create a v4l2_subdev directly.
+
+A typical state struct would look like this (where 'chipname' is replaced by
+the name of the chip):
+
+struct chipname_state {
+	struct v4l2_subdev sd;
+	...  /* additional state fields */
+};
+
+Initialize the v4l2_subdev struct as follows:
+
+	v4l2_i2c_subdev_init(&state->sd, client, subdev_ops);
+
+This function will fill in all the fields of v4l2_subdev and ensure that the
+v4l2_subdev and i2c_client both point to one another.
+
+You should also add a helper inline function to go from a v4l2_subdev pointer
+to a chipname_state struct:
+
+static inline struct chipname_state *to_state(struct v4l2_subdev *sd)
+{
+	return container_of(sd, struct chipname_state, sd);
+}
+
+Use this to go from the v4l2_subdev struct to the i2c_client struct:
+
+	struct i2c_client *client = v4l2_get_subdevdata(sd);
+
+And this to go from an i2c_client to a v4l2_subdev struct:
+
+	struct v4l2_subdev *sd = i2c_get_clientdata(client);
+
+Finally you need to make a command function to make driver->command()
+call the right subdev_ops functions:
+
+static int subdev_command(struct i2c_client *client, unsigned cmd, void *arg)
+{
+	return v4l2_subdev_command(i2c_get_clientdata(client), cmd, arg);
+}
+
+If driver->command is never used then you can leave this out. Eventually the
+driver->command usage should be removed from v4l.
+
+Make sure to call v4l2_device_unregister_subdev(sd) when the remove() callback
+is called. This will unregister the sub-device from the bridge driver. It is
+safe to call this even if the sub-device was never registered.
+
+
+The bridge driver also has some helper functions it can use:
+
+struct v4l2_subdev *sd = v4l2_i2c_new_subdev(adapter, "module_foo", "chipid", 0x36);
+
+This loads the given module (can be NULL if no module needs to be loaded) and
+calls i2c_new_device() with the given i2c_adapter and chip/address arguments.
+If all goes well, then it registers the subdev with the v4l2_device. It gets
+the v4l2_device by calling i2c_get_adapdata(adapter), so you should make sure
+that adapdata is set to v4l2_device when you setup the i2c_adapter in your
+driver.
+
+You can also use v4l2_i2c_new_probed_subdev() which is very similar to
+v4l2_i2c_new_subdev(), except that it has an array of possible I2C addresses
+that it should probe. Internally it calls i2c_new_probed_device().
+
+Both functions return NULL if something went wrong.

+   sensors and webcam controllers.
+
+   Usually these devices are controlled through an i2c bus, but other busses
+   may also be used.
+
+   The v4l2_subdev struct provides a way of accessing these devices in a
+   generic manner. Most operations that these sub-devices support fall in
+   a few categories: core ops, audio ops, video ops and tuner ops.
+
+   More categories can be added if needed, although this should remain a
+   limited set (no more than approx. 8 categories).
+
+   Each category has its own set of ops that subdev drivers can implement.
+
+   A subdev driver can leave the pointer to the category ops NULL if
+   it does not implement them (e.g. an audio subdev will generally not
+   implement the video category ops). The exception is the core category:
+   this must always be present.
+
+   These ops are all used internally so it is no problem to change, remove
+   or add ops or move ops from one to another category. Currently these
+   ops are based on the original ioctls, but since ops are not limited to
+   one argument there is room for improvement here once all i2c subdev

+
+   The ioctl ops is meant for generic ioctl-like commands. Depending on

Subject: cx18: Quiet a sometimes common warning that often has benign
 consequences

From: Andy Walls <awalls@radix.net>

cx18: Quiet a sometimes common warning that often has benign consequences.
No one probably cares that the firmware took forever to ack our command, as
they always seem to succeed whether or not the firmware acks it in a reasonable
amount of time.

Subject: cx18: Use a known open task handle when setting stream CX2341x
 parameters

From: Andy Walls <awalls@radix.net>

cx18: Use a known open task handle when setting stream CX2341x parameters
Sometimes, we might only have VBI or YUV stream open instead of an MPEG stream.
Let's make sure we use a valid task handle to perform the CX2341x control
settings.

Subject: em28xx: Cleanup GPIO/GPO setup code

From: Devin Heitmueller <devin.heitmueller@gmail.com>

Cleanup the calls to set the GPIOs and GPOs for various devices, replacing the
register number with the #define from em28xx-reg.h and converting over to using
em28xx_write_reg()

Subject: em28xx: Properly handles XCLK and I2C speed

From: Mauro Carvalho Chehab <mchehab@redhat.com>

The previous patches removed XCLK and I2C magic. Now, we finally know what those
registers do. Also, only a very few cards need different setups for those.

Instead of keeping the setups for those values inside the per-device hack magic
switch, move the uncommon values to the board-specific struct, and have a common
setup for all other boards.

So, almost 100 lines of hacking magic were removed.

A co-lateral effect of this patch is that it also fixes a bug at em28xx-core, where xclk
were set, without taking any care about not overriding a previous xclk setup.

Priority: normal

Subject: fix boards for kernels with algo_control

From: Mauro Carvalho Chehab <mchehab@redhat.com>

changeset 4ecae6da8244 removed algo_control from i2c drivers. However,
on older kernels, a dummy function to implement algo_control is required,
otherwise, an OOPS is generated.

This patch adds a backport for all i2c drivers that defines an
i2c_algorithm, except for cafe_ccic, since OLPC hardware only works
for kernels newer than 2.6.19.

Some of the backported drivers would need also extra changes to work with
older kernels, as specified on v4l/versions.txt. Yet, I decided to add
the backport for those drivers also, since the lack of algo_control doesn't
generate any compilation error, but it is enough to break the driver. So,
better to all for all boards than to allow compiling a kernel backported that
just generates OOPS.

Priority: normal

From 7a8e65e6272706e69c47c96e865ec1170c1e1564 Mon Sep 17 00:00:00 2001

Subject: em28xx: card description cleanups

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Remove unused em28xx_board.vchannels and em28xx.video_channels.
Also, .is_em2800 = 0 is not needed, as all data is zeroed by kernel loader.

The table also included a notice that svideo weren't test on Hauppauge
USB2. Remove this notice, since this input also works properly.

Subject: Remove duplicated fields on em28xx_board and em28xx structs

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Several fields are duplicated on both structs. Let's just copy em28xx_board instead.

A later cleanup could just copy the fields that are changed, in order to keep em28xx_board
const.

Priority: normal

Subject: em28xx: cleanup: saa7115 module auto-detects saa711x type

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Since saa7115 has saa711x chip auto-detection, there's no need on differenciating
it at cards table. Just use the generic name for all boards that use a philips
saa711x decoder.

Priority: normal

Subject: em28xx: improve debug messages

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Now, the first message states board names. Also, removed printing the alternate
settings by default. I2C messages are now clearer.

Priority: normal

Subject: em28xx: Improve register log format

Change log format to look more like URB transactions. In fact, setup and
IN/OUT transactions are merged. This helps to debug the driver.

Subject: em28xx: replace some magic by register descriptions where known

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Replaces all occurrences of em28xx_write_regs_req() and em28xx_write_reg()
used to setup register names by em28xx_write_reg().

Also, documents the register names that are known.

This patch were generated by this small perl script:

my %reg_map = (
	# Register table - the same as defined on parse_em28xx.pl script
);

while (<>) {
	if (m/(.*)em28xx_write_regs_req\(dev\,\s*0x00\,\s*(.*)\,\s*\"\\x(..)\",\s*1\)\;(.*)/) {
		my $reg = $2;
		my $val = $3;
		$val =~ tr/A-f/a-f/;
		$reg = $reg_map{$reg} if defined($reg_map{$reg});
		printf "$1em28xx_write_reg(dev, %s, 0x%s);$4\n", $reg, $val;
	} elsif (m/(.*)em28xx_write_regs\(dev\,\s*(.*)\,\s*\"\\x(..)\",\s*1\)\;(.*)/) {
		my $reg = $2;
		my $val = $3;
		$val =~ tr/A-f/a-f/;
		$reg = $reg_map{$reg} if defined($reg_map{$reg});
		printf "$1em28xx_write_reg(dev, %s, 0x%s);$4\n", $reg, $val;
	} else {
		print $_;
	}
}

Subject: cx18: Eliminate q_io from stream buffer handling

From: Andy Walls <awalls@radix.net>

Eliminate q_io from stream buffer handling in anticipation of upcoming
changes in buffer handling.  q_io was a holdover from ivtv and it's function
in cx18 was trivial and not necessary.  We just push things back onto the
front of q_full now, instead of maintaining a 1 buffer q_io queue.

Priority: normal

Subject: cx18: Allow more than 63 capture buffers in rotation per stream

From: Andy Walls <awalls@radix.net>

cx18: Allow more than 63 capture buffers in rotation per stream.  Implement
q_busy to hold buffers the firmware has for use.  q_free holds truly unused
buffers in a pool.  New buffers are given to the firmware as soon as the
firmware returns one, if there are any to give to the firmware.

Subject: cx18: Add module parameters for finer control over buffer allocations

From: Andy Walls <awalls@radix.net>

cx18: Add module parameters for finer control over buffer allocations.
User now has the option of setting smaller buffers to get lower
latency transfers from the encoder.  User can also now set the number
of buffers used for a stream explicitly.

Priority: normal

Subject: cx18: Avoid making firmware API calls with the queue lock held

From: Andy Walls <awalls@radix.net>

cx18: Avoid making firmware API calls with the queue lock held.  The source
of MPEG strem corruption when not holding the queue lock was found to be that
the MPEG buffer could be retrieved by the user app before it was sync'ed for
the host cpu.  Incoming buffers are now sync'ed before being put on q_full and
releasing the queue lock.  We can thus avoid the sometimes lengthy call to
the firmware for CPU_DE_SET_MDL while holding the queue lock, so we can get
better performance.

Subject: cx18: Port fix for raw/sliced VBI mixup from ivtv and cx25840

From: Andy Walls <awalls@radix.net>

This is a port of the fixes Hans Verkuil made for ivtv/cx25840:
The service_set field was used to determine whether raw or sliced VBI was
desired. This is incorrect since it is perfectly valid to select sliced VBI
with a service_set of 0.

Instead the driver should check on VIDIOC_S_FMT whether the type
field matches the raw or sliced VBI type.

Updated the cx18 driver accordingly, including an additional check in
cx18_start_v4l2_encode_stream() that didn't exist in ivtv.

Priority: normal

Subject: uvcvideo: Prevent compat.h from being included in userspace code.

From: Laurent Pinchart <laurent.pinchart@skynet.be>

When used in userspace code, the uvcvideo.h header shouldn't pull compat.h.
Make sure this won't happen by moving the #include to a __KERNEL__ protected
section.

From: Andy Walls <awalls@radix.net>

cx18: Change to per CX23418 device work queues for deferrable work handling.
Needed to support 2.6.22 and earlier kernels that can't selectively cancel
work orders.  Also will provide slightly better performance on SMP systems.

Subject: cx18: Change work_queue teardown to work for kernels earlier than
 2.6.22

From: Andy Walls <awalls@radix.net>

For kernels earlier than 2.6.22, we can't cancel work, so we have to flush the
work queue to completion before destroying it.

Priority: normal

Subject: em28xx: move gpio lines into board table description

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Instead of a large, ugly switch specifying the gpio tables for each
device, let's move it into the boards struct. This also helps to see
what boards have already the gpio's for DVB.

Priority: normal

Subject: em28xx: fix tuner absent entries

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Before this patch, several devices without tuner were kept the value 0
for tuner_type. However, this means TUNER_TEMIC_PAL. Replace those
entries for the proper TUNER_ABSENT value.

Subject: em28xx: Add support for suspend the device when not used

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Several chips may be turned off when the device is not used, like audio,
video and dvb demods. This patch adds a gpio callback at the core
structs to allow turning off such devices.

Subject: cx18: cx18_writel_expect() should not declare success on a PCI read
 error

From: Andy Walls <awalls@radix.net>

cx18: cx18_writel_expect() should not declare success on a PCI read error.
This removes the potential for cx18_write*_expect() calls to not
accomplish a PCI write successfully as expected.  The CX18-AV core uses the
*expect() calls often and this may be the source of intermittent audio
problems and standands switching problems.

Subject: dib0700: Stop repeating after user stops pushing button

From: Devin Heitmueller <devin.heitmueller@gmail.com>

A user noticed that there would continue to be 4-6 keypresses even after the
user stopped holding down the button.  This was because we were not reading
the bulk pipe faster than the firmware was injecting information, which would
result in a backlog.

Make the query interval faster, and increase the number of cycles before we
start repeating to compensate.

Thanks to Knud Poulsen <knud.poulsen@nokia.com> for pointing this out.

Subject: [PATCH] Cablestar 2 I2C retries (fix CableStar2 support)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

From: Antti Seppälä <a.seppala+linux-dvb@gmail.com>

At some point the Flexcop driver was changed to support newer Flexcop cards.
These modifications however broke the detection of Cablestar 2 DVB-C cards.

The reason is that the earlier version of the driver used to retry
unsuccessful i2c operations. The demodulator of Cablestar 2 cards (stv0297)
seems to be very dependent on these retries and adding them back fixes
Cablestar detection.

This patch restores this behaviour for the CableStar2.

Subject: soc-camera: merge .try_bus_param() into .try_fmt_cap()
 .try_bus_param() method from struct soc_camera_host_ops is only called at one
 location immediately before .try_fmt_cap(), there is no value in keeping
 these two methods separate, merge them.

Subject: soc-camera: let camera host drivers decide upon pixel format Pixel
 format requested by the user is not necessarily the same, as what a sensor
 driver provides. There are situations, when a camera host driver provides the
 required format, but requires a different format from the sensor. Further,
 the list of formats, supported by sensors is pretty static and can be pretty
 good described with a constant list of structures. Whereas decisions, made by
 camera host drivers to support requested formats can be quite complex,
 therefore it is better to let the host driver do the work.

From 0245bbfa8052eabd0398e5b0d92345feabfcfafc Mon Sep 17 00:00:00 2001
From: Guennadi Liakhovetski <lyakh@axis700.grange>
Date: Mon, 1 Dec 2008 13:45:21 +0100
Subject: soc-camera: simplify naming We anyway don't follow the s_fmt_vid_cap
 / g_fmt_vid_cap / try_fmt_vid_cap naming, and soc-camera is so far only about
 video capture, let's simplify operation names a bit further. set_fmt_cap /
 try_fmt_cap wasn't a very good choice too.

Subject: soc-camera: pixel format negotiation - core support Allocate and fill
 a list of formats, supported by this specific camera-host combination. Use it
 for format enumeration. Take care to stay backwards-compatible.

Camera hosts rely on sensor formats available, as well as
host specific translations. We add a structure so that hosts
can define a translation table and use it for format check
and setup.

Subject: pxa-camera: pixel format negotiation Use the new format-negotiation
 infrastructure, support all four YUV422 packed and the planar formats.

The new translation structure enables to build the format
list with buswidth, depth, host format and camera format
checked, so that it's not done anymore on try_fmt nor
set_fmt.

Subject: drivers/media/video/cx88/cx88-alsa.c: Adjust error-handling code

From: Julia Lawall <julia@diku.dk>

In the function cx88_audio_initdev, the value card has been created using
snd_card_new.  The other error handling code in this function frees the
value using snd_card_free.  I have thus changed the first error case to do
the same.  On the other hand, it may be that card is not sufficiently
initialized at this point to use snd_card_free, in which case something
else should be done to free the memory in the error case.

In the function snd_cx88_create the call kfree(chip) in one error case
looks suspicious, both because it is not done in the other error code, and
because chip points into the middle of the memory allocated by
snd_card_new, ie it is not itself associated with a separate kmalloc.
Therefore I have removed it.

The semantic match that finds the first problem is as follows:

Subject: gspca - ov534: Fix frame size so we don't miss the last pixel.

From: Jim Paris <jim@jtan.com>

The frame size is too small, so we lose the last YUYV pixel.
Fix the setup and remove the last_pixel hack.

Date: Thu, 4 Dec 2008 08:52:40 +0100
Subject: gspca - ov534: Frame transfer improvements.

From: Jim Paris <jim@jtan.com>

The indirect registers at 0x1c/0x1d control frame settings.  If we
leave the values at 0x0a and 0x0b at their reset-time defaults, frame
data from the camera matches the UVC payload format.  This lets us
better reassemble the data into frames and know when data was lost.

This also lets us relax the bulk_size requirement from 600K to 2K,
which should help systems on with limited RAM (like the PS3).

Subject: tuner-xc2028: powers device of when not used

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Since the firmware load is now fast on most boards, better to keep the tuner
off by default. A modprobe parameter were added to keep the old behavior,
to be used by old devices.

Priority: normal

Subject: em28xx: turn off tuner when not used

From: Mauro Carvalho Chehab <mchehab@redhat.com>

em28xx devices generally get hot when xc3028 tuner is powered on. This
patch solves this by turning power off when the device is not used, at the
expense of having a higher load time, when calling a TV application.

Since firmware load happens on 1 or 2 seconds on most devices, this is not a pain.

Also, it helps to save the planet by saving some power :)

Subject: uvcvideo: Add nodrop module parameter to turn incomplete frame drop
 off.

From: Laurent Pinchart <laurent.pinchart@skynet.be>

The driver drops incomplete uncompressed video frames to avoid confusing
userspace with corrupt data. Add a nodrop module parameter to turn that
behaviour off and make all frames available to userspace.

From: Laurent Pinchart <laurent.pinchart@skynet.be>

Bogus controls currently include processing unit auto controls for which no
corresponding manual control is available. Such auto controls make little
sense if any, and are known to crash at least the SiGma Micro webcam.

Subject: tda827x: fix returned frequency

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Probably due to a removed code, tda827x were doing some wrong calculus at the
returned frequency. I suspect that the original idea were to return the
programmed divisor converted into frequency again.

However, the current code is sometimes multiplying the programmed frequency by
62500, and, on other cases, like radio, it dividing it by 1000.

Instead of doing such math, let's just store the frequency value as requested by
the caller module.

Subject: tda8290: fix FM radio

From: Mauro Carvalho Chehab <mchehab@redhat.com>

tda8290 were using some random video standard for FM. This results on random
errors. Instead, program tda8290 in expert mode, using a configuration near the
one specified on NXP datasheet for tda8295 (available on their site).

Also, properly display that the device is on radio mode.

+How to set up the Technisat devices
+===================================
+
+1) Find out what device you have
+================================
+
+First start your linux box with a shipped kernel:
+lspci -vvv for a PCI device (lsusb -vvv for an USB device) will show you for example:
+02:0b.0 Network controller: Techsan Electronics Co Ltd B2C2 FlexCopII DVB chip / Technisat SkyStar2 DVB card (rev 02)
+
+dmesg | grep frontend may show you for example:
+DVB: registering frontend 0 (Conexant CX24123/CX24109)...
+
+2) Kernel compilation:
+======================
+
+If the Technisat is the only TV device in your box get rid of unnecessary modules and check this one:
+"Multimedia devices" => "Customise analog and hybrid tuner modules to build"
+In this directory uncheck every driver which is activated there.
+
+Then please activate:
+2a) Main module part:
+
+a.)"Multimedia devices" => "DVB/ATSC adapters" => "Technisat/B2C2 FlexcopII(b) and FlexCopIII adapters"
+b.)"Multimedia devices" => "DVB/ATSC adapters" => "Technisat/B2C2 FlexcopII(b) and FlexCopIII adapters" => "Technisat/B2C2 Air/Sky/Cable2PC PCI" in case of a PCI card OR

+d.)"Multimedia devices" => "DVB/ATSC adapters" => "Technisat/B2C2 FlexcopII(b) and FlexCopIII adapters" => "Enable debug for the B2C2 FlexCop drivers"
+Notice: d.) is helpful for troubleshooting
+
+2b) Frontend module part:
+

 linux/drivers/media/video/saa7134/Kconfig description: media Kconfigs: fix
 bugzilla #12204

From: Mauro Carvalho Chehab <mchehab@redhat.com>

When the tuner modules were moved to common/tuners, a separate customize
option were added for tuners. However, the automatic selection of the
tuners were still using the older option.

This causes that the automatic selection to fail, if DVB_FE_CUSTOMISE is
selected. Also, since those tuners are now under MEDIA_TUNER_CUSTOMIZE
menu, if you unset MEDIA_TUNER_CUSTOMIZE, you can't manually select the
tuners.

This patch fixes this error by replacing DVB_FE_CUSTOMISE by
MEDIA_TUNER_CUSTOMIZE on all places were a tuner is selected.

The patch were generated by this small script:

for i in `find drivers/media -name Kconfig`; do
  cat $i|perl -ne 's/(MEDIA_TUNER.*)DVB_FE_CUSTOMISE/\1MEDIA_TUNER_CUSTOMIZE/; print $_' >a
  mv a $i
done

A manual reordering were done to have the media selects just after the
dvb ones.

Subject: v4l2: Add camera zoom controls

From: Laurent Pinchart <laurent.pinchart@skynet.be>

The zoom controls move the zoom lens group to a an absolute position, as a
relative displacement or at a given speed until reaching physical device
limits. Positive values move the zoom lens group towards the telephoto
direction, negative values towards the wide-angle direction.

Subject: v4l2: Add privacy control

From: Laurent Pinchart <laurent.pinchart@skynet.be>

The privacy control prevents video from being acquired by the camera. A true
value indicates that no image can be captured. Devices that implement the
privacy control must support read access and may support write access.

Subject: cx18: Refine the firmware load and firmware startup process

From: Andy Walls <awalls@radix.net>

Refine the firmware load and firmware startup process.  Significant changes
are to ensure the SCB and IPC area are correct before starting up the firmware,
and letting the CPU firmware start up the APU firmware for us.

Priority: normal

Subject: v4l2-compat: test for unlocked_ioctl as well.

From: Hans Verkuil <hverkuil@xs4all.nl>

The v4l_compat_ioctl32() function only tested for the presence of the
ioctl op, not for unlocked_ioctl. So it would always return an error
when used with drivers that use unlocked_ioctl instead of ioctl.

Priority: high

Subject: em28xx: vidioc_try_fmt_vid_cap() doesn't need any lock

From: Mauro Carvalho Chehab <mchehab@redhat.com>

vidioc_try_fmt_vid_cap() just checks if a given resolution is supported.
It doesn't touch on struct em28xx device descriptor. so, there's no need
to lock.

While there, use unlikely() for those values that aren't likely to
occur.

Subject: em28xx: fix/improve em28xx locking schema

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Changes/fixes on em28xx dev->lock:

- em28xx_init_dev() were unlocking without a previous lock;

- some read ioctls need to lock after the removal of KBL, since a write
  may be happening at the same time an ioctl is reading;

- keep the device locked during all device initialization;

- lock/unlock while reading/writing registers.

Subject: em28xx: fix NULL pointer dereference in call to VIDIOC_INT_RESET
 command

From: Devin Heitmueller <dheitmueller@linuxtv.org>

Fix a NULL pointer dereference that would occur if the video decoder tied to
the em28xx supports the VIDIOC_INT_RESET call (for example: the cx25840 driver)

Priority: high

Don't operate under the assumption that every device that uses the em2820
default USB ID is a Prolink PlayTV USB.  We have an eeprom hash, so use that,
since otherwise we cannot support other devices with the 2820 default USB ID
(such as the ADS Tech Instant TV USB USBAV-704)

Subject: xc5000: remove init_fw option

From: Devin Heitmueller <dheitmueller@linuxtv.org>

The init_fw option was broken for the HVR-950q because we would call the reset
callback inside of dvb_attach() and the callback had not been setup yet.

Michael Krufky (who added the init_fw feature) says it's no longer required,
so just remove the option completely.

Thanks to user Zzeiss from #linuxtv chat for reporting the issue and
Michael Krufky <mkrufky@linuxtv.org> for proposing the fix.

Subject: tuner-xc2028: allow printing stack trace as debug on sleep code

From: Mauro Carvalho Chehab <mchehab@redhat.com>

tuner-xc3028 can be put to sleep to save power. However, if not properly
recovered from sleep, the device won't work. It is noticed that some
devices doesn't recover properly, so let's add a dump_stack() as a debug
option, to allow us to track when this happens.

Subject: dvb-core: don't add an event when in ONE SHOT mode for algo type HW

From: Darron Broad <darron@kewl.org>

It has been noticed that in HW tuning mode in cx24123.c that
a check is made to not alter the status var when in one shot
mode, a simpler solution is to not update here for all cards.

Subject: cx24116: change to ALGO_HW

Slow tuning, EG:

status 1f | signal c040 | snr bb33 | ber 00000000 | unc 00000000 | FE_HAS_LOCK

Appears to be resolved by dropping zig-zag tuning and relying on
hardware only:

> szap-s2 -r -c 39.FTATV "1=Pgm1;Net1"
reading channels from file '39.FTATV'
zapping to 3 '1=Pgm1;Net1':
delivery DVB-S, modulation QPSK
sat 0, frequency 11140 MHz V, symbolrate 1425000, coderate 5/6, rolloff 0.35
vpid 0x0200, apid 0x0300, sid 0x0001
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
status 01 | signal ff80 | snr 0000 | ber 00000000 | unc 00000000 |
status 1f | signal ff80 | snr c199 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal c040 | snr c199 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal ff80 | snr c199 | ber 00000000 | unc 00000000 | FE_HAS_LOCK

Tuning to a weaker channel shows that the hardware recovers sync:

status 1f | signal fe40 | snr 5199 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 03 | signal fd40 | snr 5000 | ber 00000000 | unc 00000000 |

status 01 | signal fd80 | snr 4e66 | ber 00000000 | unc 00000000 |
status 1f | signal fe40 | snr 5000 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 03 | signal fe40 | snr 5000 | ber 00000000 | unc 00000000 |
status 01 | signal fd80 | snr 0000 | ber 00000000 | unc 00000000 |
status 1f | signal fe40 | snr 5199 | ber 00000000 | unc 00000000 | FE_HAS_LOCK

Also, tuning, moving the dish and then restoring the dish also retunes.

Subject: cx88: advise/acquire clean-up for HVR-1300/3000/4000

From: Darron Broad <darron@kewl.org>

This cleans-up the advise/acquire methods.

This has been tested on the hvr-1300/4000 and assumed to be
correct on the hvr-3000.

This update also fixes analogue tuning on the hvr-1300
when in blackbird mode.

- Video Sampling
-Digital video is a sampled form of analog video. The most common sampling schemes in use today are:
-		  Pixel Clock   Horiz    Horiz    Vert
-		   Rate         Total    Active
-NTSC square pixel  12.27 MHz    780      640      525
-NTSC CCIR-601      13.5  MHz    858      720      525
-NTSC 4FSc          14.32 MHz    910      768      525
-PAL  square pixel  14.75 MHz    944      768      625
-PAL  CCIR-601      13.5  MHz    864      720      625
-PAL  4FSc          17.72 MHz   1135      948      625
-
-For the CCIR-601 standards, the sampling is based on a static orthogonal sampling grid. The luminance component (Y) is sampled at 13.5 MHz, while the two color difference signals, Cr and Cb are sampled at half that, or 6.75 MHz. The Cr and Cb samples are colocated with alternate Y samples, and they are taken at the same position on each line, such that one sample is coincident with the 50% point of the falling edge of analog sync. The samples are coded to either 8 or 10 bits per component.

Subject: v4l2-dev: check for parent device in get_index.

From: Hans Verkuil <hverkuil@xs4all.nl>

get_index requires a valid parent device in order to discover which
indices are in use. Some drivers (e.g. pvrusb2) do not set the parent
device. In that case just return 0.

@@ -359,4 +362,159 @@ Both functions return NULL if something went wrong.
 struct video_device
 -------------------
 
-Not yet documented.
+The actual device nodes in the /dev directory are created using the
+video_device struct (v4l2-dev.h). This struct can either be allocated
+dynamically or embedded in a larger struct.
+
+To allocate it dynamically use:
+
+	struct video_device *vdev = video_device_alloc();
+
+	if (vdev == NULL)
+		return -ENOMEM;
+
+	vdev->release = video_device_release;
+
+If you embed it in a larger struct, then you must set the release()
+callback to your own function:
+
+	struct video_device *vdev = &my_vdev->vdev;
+
+	vdev->release = my_vdev_release;
+
+The release callback must be set and it is called when the last user
+of the video device exits.
+
+The default video_device_release() callback just calls kfree to free the
+allocated memory.
+
+You should also set these fields:
+
+- parent: set to the parent device (same device as was used to register
+  v4l2_device).
+- name: set to something descriptive and unique.
+- fops: set to the file_operations struct.
+- ioctl_ops: if you use the v4l2_ioctl_ops to simplify ioctl maintenance
+  (highly recommended to use this and it might become compulsory in the
+  future!), then set this to your v4l2_ioctl_ops struct.
+
+If you use v4l2_ioctl_ops, then you should set .unlocked_ioctl to
+__video_ioctl2 or .ioctl to video_ioctl2 in your file_operations struct.
+
+
+video_device registration
+-------------------------
+
+Next you register the video device: this will create the character device
+for you.
+
+	err = video_register_device(vdev, VFL_TYPE_GRABBER, -1);
+	if (err) {
+		video_device_release(vdev); // or kfree(my_vdev);
+		return err;
+	}
+
+Which device is registered depends on the type argument. The following
+types exist:
+
+VFL_TYPE_GRABBER: videoX for video input/output devices
+VFL_TYPE_VBI: vbiX for vertical blank data (i.e. closed captions, teletext)
+VFL_TYPE_RADIO: radioX for radio tuners
+VFL_TYPE_VTX: vtxX for teletext devices (deprecated, don't use)
+
+The last argument gives you a certain amount of control over the device
+kernel number used (i.e. the X in videoX). Normally you will pass -1 to
+let the v4l2 framework pick the first free number. But if a driver creates
+many devices, then it can be useful to have different video devices in
+separate ranges. For example, video capture devices start at 0, video
+output devices start at 16.
+
+So you can use the last argument to specify a minimum kernel number and
+the v4l2 framework will try to pick the first free number that is equal
+or higher to what you passed. If that fails, then it will just pick the
+first free number.
+
+Whenever a device node is created some attributes are also created for you.
+If you look in /sys/class/video4linux you see the devices. Go into e.g.
+video0 and you will see 'name' and 'index' attributes. The 'name' attribute
+is the 'name' field of the video_device struct. The 'index' attribute is
+a device node index that can be assigned by the driver, or that is calculated
+for you.
+
+If you call video_register_device(), then the index is just increased by
+1 for each device node you register. The first video device node you register
+always starts off with 0.
+
+Alternatively you can call video_register_device_index() which is identical
+to video_register_device(), but with an extra index argument. Here you can
+pass a specific index value (between 0 and 31) that should be used.
+
+Users can setup udev rules that utilize the index attribute to make fancy
+device names (e.g. 'mpegX' for MPEG video capture device nodes).
+
+After the device was successfully registered, then you can use these fields:
+
+- vfl_type: the device type passed to video_register_device.
+- minor: the assigned device minor number.
+- num: the device kernel number (i.e. the X in videoX).
+- index: the device index number (calculated or set explicitly using
+  video_register_device_index).
+
+If the registration failed, then you need to call video_device_release()
+to free the allocated video_device struct, or free your own struct if the
+video_device was embedded in it. The vdev->release() callback will never
+be called if the registration failed, nor should you ever attempt to
+unregister the device if the registration failed.
+
+
+video_device cleanup
+--------------------
+
+When the video device nodes have to be removed, either during the unload
+of the driver or because the USB device was disconnected, then you should
+unregister them:
+
+	video_unregister_device(vdev);
+
+This will remove the device nodes from sysfs (causing udev to remove them
+from /dev).
+
+After video_unregister_device() returns no new opens can be done.
+
+However, in the case of USB devices some application might still have one
+of these device nodes open. You should block all new accesses to read,
+write, poll, etc. except possibly for certain ioctl operations like
+queueing buffers.
+
+When the last user of the video device node exits, then the vdev->release()
+callback is called and you can do the final cleanup there.
+
+
+video_device helper functions
+-----------------------------
+
+There are a few useful helper functions:
+
+You can set/get driver private data in the video_device struct using:
+
+void *video_get_drvdata(struct video_device *dev);
+void video_set_drvdata(struct video_device *dev, void *data);
+
+Note that you can safely call video_set_drvdata() before calling
+video_register_device().
+
+And this function:
+
+struct video_device *video_devdata(struct file *file);
+
+returns the video_device belonging to the file struct.
+
+The final helper function combines video_get_drvdata with
+video_devdata:
+
+void *video_drvdata(struct file *file);
+
+You can go from a video_device struct to the v4l2_device struct using:
+
+struct v4l2_device *v4l2_dev = dev_get_drvdata(vdev->parent);

Subject: cs5345: convert to v4l2_subdev and fix broken s_ctrl.

From: Hans Verkuil <hverkuil@xs4all.nl>

Converted to v4l2_subdev. While doing that I also discovered a stray 'break'
that broke the S_CTRL handling. Fixed that as well.

Priority: normal

Subject: v4l2-dev: use the release callback from device instead of cdev

From: Hans Verkuil <hverkuil@xs4all.nl>

Instead of relying on the cdev release callback we should rely on the
release callback from the device struct. This requires that we use
get_device/put_device to do proper refcounting. In order to do this
safely v4l2-dev.c now sets up its own file_operations that call
out to the driver's ops.

Subject: em28xx: Fix a bug that were putting xc2028/3028 tuner to sleep

From: Mauro Carvalho Chehab <mchehab@redhat.com>

The changeset 78aa52a159cf introduced a bug on em28xx: buffer setup should be
awaking xc3028. Instead, since we didn't specify the tuner mode, the device
were going to sleep, due to the lack of tuner mode when asking tuner to handle
VIDIOC_S_FREQUENCY:

xc2028 0-0061: Device is Xceive 3028 version 1.0, firmware version 2.7
xc2028 0-0061: divisor= 00 00 14 d0 (freq=83.250)
xc2028 0-0061: Putting xc2028/3028 into poweroff mode.
xc2028 0-0061: Printing sleep stack trace:
Pid: 10936, comm: mplayer Tainted: P   M      2.6.27.8 #1

Call Trace:

Subject: Convert GP8PSK module to use S2API

From: Alan Nisota <alannisota@gmail.com>

This patch converts the gp8psk module to use the S2API.
It pretends to be  DVB-S2 capable in order to allow the various
supported modulations (8PSK, QPSK-Turbo, etc), and keep software
compatibility with the S2API patches for Mythtv and VDR.

Subject: cx18: Disable locking of Video and Audio PLL for analog captures

From: Andy Walls <awalls@radix.net>

Disable AV_LOCK, locking of audio PLL to video PLL in the cx18-av-core for
analog captures.  It seems to have adverse effects on captures from
SVideo and CVBS sources with current clock & crystal settings in the driver.

Many thanks to Jeff Campbell and Mike Bradley for reporting this problem,
and suggesting the solution and performing extensive testing to support their
suggestion.

Subject: cx18: Use a consistent crystal value for computing all PLL parameters

From: Andy Walls <awalls@radix.net>

Use a consistent crystal value of 28.636360 MHz for computing all PLL
parameters so clocks don't have relative error due to assumed crystal
value mismatches.  Also aimed to have all PLLs run their VOCs at close to
400 MHz to minimze the error of these PLLs as frequency synthesizers. Also
set the VDCLK and AIMCLK PLLs to sane values before the APU and CPU firmware
are loaded.  Also fixed I2S Master clock dividers.

Many thanks to Mike Bradley and Jeff Campbell for reporting this problem and
suggesting the solution, researching and experimenting, and performing
extensive testing to support their suggested solution.

Subject: em28xx: Add suport for debugging AC97 anciliary chips

From: Mauro Carvalho Chehab <mchehab@redhat.com>

Subject: v4l2-dev: allow drivers to pass v4l2_device as parent

From: Hans Verkuil <hverkuil@xs4all.nl>

Drivers that use v4l2_device can set that as parent pointer in the v4l2_dev
field instead of using the struct device parent field.

This allows v4l2-dev.c to check whether this driver is v4l2_device based,
and if so then it can offer additional services.
