Subject: uvcvideo: Restructure the driver to support multiple simultaneous
 streams.

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

As a first step towards multiple streaming interfaces support, reorganize the
driver's data structures to cleanly separate video control and video streaming
data.

Priority: normal

Subject: uvcvideo: Multiple streaming interfaces support

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

Restructure the UVC descriptors parsing code to handle multiple streaming
interfaces. The driver now creates a uvc_video_chain instance for each chain
detected in the UVC control interface descriptors, and tries to register one
video device per streaming endpoint.

Priority: normal

Subject: uvcvideo: Avoid flooding the kernel log with "unknown event type"
 messages

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

The iSight sends non-UVC status events through the interrupt endpoint. Those
invalid events are reported to the kernel log, resulting in a log flood.

Only log the events when the UVC_TRACE_STATUS flag is set.

Priority: high

Subject: sms1xxx: fix build warning: unused variable 'board'

From: Michael Krufky <mkrufky@kernellabs.com>

Remove the following build warning:

sms-cards.c: In function 'sms_board_event':
sms-cards.c:120: warning: unused variable 'board'

Thanks to Hans Verkuil for pointing this out.

The problem code has been #if 0'd for now, this will likely be
used again in the future, once the event interface is complete.

Priority: high

Subject: cx88: fix regression in tuning for Geniatech X8000 MT

From: Devin Heitmueller <dheitmueller@kernellabs.com>

The introduction of the zl10353 i2c gate control broke support for the
Geniatech board (which is not behind an i2 gate).  Add the needed parameter.

Priority: high

Subject: cx88: Disable xc3028 power management for Geniatech x8000

From: Devin Heitmueller <dheitmueller@kernellabs.com>

A user discovered that the Geniatech x8000 encountered a regression when
the xc3028 power management was introduced.  The xc3028 never recovers after
setting the powerdown register, which is probably because the xc3028 reset
GPIO is not properly configured.  Since I do not have access to the hardware
and thus cannot determine the correct GPIO configuration, just disable xc3028
power management on this board, which fixes the regression.

Thanks to user "ritec" for reporting the issue and testing the fix.

Priority: high

Subject: em28xx: fix V4L2 API compliance: don't expose audio inputs for
 devices without it

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

V4L2 API (chapter 1.5) states that:

	Drivers must implement all input ioctls when the device has one
	or more inputs, all output ioctls when the device has one or more outputs.
	When the device has any audio inputs or outputs the driver must set the
	V4L2_CAP_AUDIO flag in the struct v4l2_capability returned by the
	VIDIOC_QUERYCAP ioctl.

So, devices without audio input should return -EINVAL.

Subject: radio-si470x: separate common and usb code

This patch is a preceding work to add the i2c interface of si470x.
The si470x directory includes a common file and usb specific file and
header file.
The part unrelated with usb interface and i2c interface exists in
radio-si470x-common.c file, and The usb specific part exists in
radio-si470x-usb.c file.

Signed-off-by: Joonyoung Shim <jy0922.shim@samsung.com>

Small changes, due to new include "linux/smp_lock.h".

+config USB_SI470X
+	tristate "Silicon Labs Si470x FM Radio Receiver support with USB"
+	depends on USB && RADIO_SI470X
+	---help---
+	  This is a driver for USB devices with the Silicon Labs SI470x
+	  chip. Currently these devices are known to work:
+	  - 10c4:818a: Silicon Labs USB FM Radio Reference Design
+	  - 06e1:a155: ADS/Tech FM Radio Receiver (formerly Instant FM Music)
+	  - 1b80:d700: KWorld USB FM Radio SnapMusic Mobile 700 (FM700)
+	  - 10c5:819a: Sanei Electric FM USB Radio (aka DealExtreme.com PCear)
+
+	  Sound is provided by the ALSA USB Audio/MIDI driver. Therefore
+	  if you don't want to use the device solely for RDS receiving,
+	  it is recommended to also select SND_USB_AUDIO.
+
+	  Please have a look at the documentation, especially on how
+	  to redirect the audio stream from the radio to your sound device:
+	  Documentation/video4linux/si470x.txt
+
+	  Say Y here if you want to connect this type of radio to your
+	  computer's USB port.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called radio-usb-si470x.

+ *		Version 1.0.1
+ *		- Improved error handling, every function now returns errno
+ *		- Improved multi user access (start/mute/stop)
+ *		- Channel doesn't get lost anymore after start/mute/stop
+ *		- RDS support added (polling mode via interrupt EP 1)
+ *		- marked default module parameters with *value*
+ *		- switched from bit structs to bit masks
+ *		- header file cleaned and integrated
+ * 2008-01-14	Tobias Lorenz <tobias.lorenz@gmx.net>
+ * 		Version 1.0.2
+ * 		- hex values are now lower case
+ * 		- commented USB ID for ADS/Tech moved on todo list
+ * 		- blacklisted si470x in hid-quirks.c
+ * 		- rds buffer handling functions integrated into *_work, *_read
+ * 		- rds_command in si470x_poll exchanged against simple retval
+ * 		- check for firmware version 15
+ * 		- code order and prototypes still remain the same
+ * 		- spacing and bottom of band codes remain the same
+ * 2008-01-16	Tobias Lorenz <tobias.lorenz@gmx.net>
+ *		Version 1.0.3
+ * 		- code reordered to avoid function prototypes
+ *		- switch/case defaults are now more user-friendly
+ *		- unified comment style
+ *		- applied all checkpatch.pl v1.12 suggestions
+ *		  except the warning about the too long lines with bit comments
+ *		- renamed FMRADIO to RADIO to cut line length (checkpatch.pl)
+ * 2008-01-22	Tobias Lorenz <tobias.lorenz@gmx.net>
+ *		Version 1.0.4
+ *		- avoid poss. locking when doing copy_to_user which may sleep

From b17608ffc4ff53dbf7bab4bbcdb1d3ad808e9ff0 Mon Sep 17 00:00:00 2001
From: Tobias Lorenz <tobias.lorenz@gmx.net>
Date: Sun, 9 Aug 2009 19:23:35 +0200
Subject: radio-si470x: add i2c driver for si470x

This patch supports i2c interface of si470x. The i2c specific part
exists in radio-si470x-i2c.c file and the common part uses
radio-si470x-common.c file. The '#if defined' is inserted inevitably
because of parts used only si470x usb in the common file.

The current driver version doesn't support the RDS.

Subject: em28xx: Move the non-board dependent part to be outside
 em28xx_pre_card_setup()

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

em28xx_pre_card_setup() is meant to contain board-specific initialization. Also,
as autodetection sometimes occur only after having i2c bus enabled, this
function may need to be called later.

Moving those setups to happen outside the function avoids calling it twice without
need and without duplicating output lines at dmesg.

Subject: em28xx: Fix artifacts with Silvercrest webcam

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

Silvercrest mt9v011 sensor produces a 640x480 image. However,
previously, the code were getting only half of the lines and merging two
consecutive frames to "produce" a 640x480 image.

With the addition of progressive mode, now em28xx is working with a full
image. However, when the number of lines is bigger than 240, the
beginning of some odd lines are filled with blank.

After lots of testing, and physically checking the device for a Xtal, it
was noticed experimentally that mt9v011 is using em28xx XCLK as its
clock. Due to that, changing XCLK value changes the maximum speed of the
stream.

At the tests, it were possible to produce up to 32 fps, using a 30 MHz
XCLK. However, at that rate, the artifacts happen even at 320x240. Lower
values of XCLK produces artifacts only at 640x480.

At some values of xclk (for example XCLKK = 6 MHz, 640x480), it is
possible to see an invalid sucession of artifacts with this pattern:

.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
..xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
...xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
....xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
..xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
...xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
....xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

(where the dots represent the blanked pixels)

So, it seems that a waveform in the format of a ramp is interferring at
the image.

The cause of this interference is currently unknown. Some possibilities
are:
	- electrical interference (maybe this device is broken?);
	- some issue at mt9v011 programming;
	- some bug at em28xx chip.

So, for now, let's be conservative and use a value of XCLK that we know
for sure that it won't cause artifacts.

As I'm waiting for more of such devices with different em28xx chipset
revisions, I'll have the opportunity to double check the issue with
other pieces of hardware.

Later patches can vary XCLK depending on the vertical resolutions, if a
proper fix is not discovered.

Subject: em28xx: fix: avoid having a bad colored image with webcams

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

Register 0x13 seems to be a sort of image control, maybe gamma. Lower
values produce better images, while higher values increases the contrast
and shifts colors to green. 0xff produces a black image.

If this register is left alone, a random value can be found at the
register, producing weird results.

This register doesn't seem to affect tv streams.

From 61fe68b877246eb29fc7cccb96a73ffa3c7267fe Mon Sep 17 00:00:00 2001
From: Tobias Lorenz <tobias.lorenz@gmx.net>
Date: Mon, 10 Aug 2009 23:44:14 +0200
Subject: I2C cleanups and version checks

The structure and comments of the I2C part have been adopted to fit to the
USB part.

Some additional cleanups and precisements have been made to the version
detection and checking functionality to clearly separate HW/SW/FW version.

Subject: saa7134: fix the radio on Avermedia GO 007 FM

From: hermann pitton <hermann-pitton@arcor.de>

We have support for radio on saa7133/35/31e cards with tda8290/8275(a)
and 5.5MHz ceramic filter on the bridge chips since a while.

It was previously not tested, if this card supports it too, but the old
"ghost" radio with wrong filters doesn't work anymore.

Thanks go to Pham Thanh Nam and Laszlo Kustan for reporting it working
on that input.

Subject: mt9v011: Add support for controlling frame rates

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

Implement g_parm/s_parm ioctls. Those are used to check the current
frame rate (in fps) and to set it to a value. In practice, there are
only 15 possible different speeds, due to chip limits.

Subject: em28xx: Allow changing fps on webcams

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

em28xx doesn't have temporal scaling. However, on webcams, sensors are
capable of changing the output rate. So, VIDIOC_[G|S]_PARM ioctls should
be passed to the sensor for it to properly set frame rate.

Subject: em28xx: properly reports some em2710 chips

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

As reported by hermann pitton <hermann-pitton@arcor.de>, some devices
has a different chip id for em2710 (likely the older ones):

em28xx: New device @ 480 Mbps (eb1a:2710, interface 0, class 0)
em28xx #0: Identified as EM2710/EM2750/EM2751 webcam grabber (card=22)
em28xx #0: em28xx chip ID = 17

Subject: em28xx: fix: don't do image interlacing on webcams

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

Due to historical reasons, em28xx driver gets two consecutive frames and
fold them into an unique framing, doing interlacing. While this works
fine for TV images, this produces two bad effects with webcams:

1) webcam images are progressive. Merging two consecutive images produce
interlacing artifacts on the image;

2) since the driver needs to get two frames, it reduces the maximum
frame rate by two.

Subject: em28xx: Adjust Silvercrest xtal frequency

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

We don't know the xtal frequency of Silvercrest, but we need to have
some value in order to allow controlling the frame rate frequency. The
value is probably still wrong, since the manufacturer announces this
device as being capable of 30fps, but the maximum we can get is
13.5 fps.

Subject: hdpvr: add missing initialization of current_norm

From: Hans Verkuil <hverkuil@xs4all.nl>

Drivers should either set current_norm or supply a g_std callback.

The hdpvr driver does neither. Since it initializes to a 60 Hz format
I've initialized the current_norm to NTSC | PAL_M | PAL_60 which is the
60 Hz subset of tvnorms.

Subject: v4l2-ioctl: fix G_STD and G_PARM default handlers

From: Hans Verkuil <hverkuil@xs4all.nl>

The v4l core supplies default handlers for G_STD and G_PARM. However, both
default handlers are buggy.

This patch fixes the following:

1) If no g_std is supplied and current_norm == 0, then this driver does not
   support TV video standards (e.g. a radio or webcam driver). Return
   -EINVAL. This ensures that there is no bogus VIDIOC_G_STD support for
   such drivers.

2) The default VIDIOC_G_PARM handler used current_norm instead of first
   checking if the driver supported g_std and calling that to get the norm.
   It also didn't check if current_norm was 0, since in that case the driver
   does not support TV standards (or no standard was set at all) and the
   default handler should return -EINVAL.

Note that I am very unhappy with these default handlers: I think they
basically behave like some very strange and unexpected side-effect.

Subject: cx88: add support for WinFast DTV2000H rev. J

From: Vlastimil Labsky <vlasta.labsky@gmail.com>

I updated and simplyfied patch from Zbynek Hrabovsky for recent kernel.
It enables autodetection of card, sound in analog TV , sound in FM radio
and switching between antenna and cable RF input.  Radio tuner still
doesn't work, I don't even know how it works.  Some guys wrote me that FM
radio works with TV tuner used instead of radio part (symlink video0 ->
radio0).

Subject: Use kzalloc for frontend states to have struct dvb_frontend properly

From: Matthias Schwarzott <zzam@gentoo.org>

This patch changes most frontend drivers to allocate their state structure via
kzalloc and not kmalloc. This is done to properly initialize the
embedded "struct dvb_frontend frontend" field, that they all have.

The visible effect of this struct being uninitalized is, that the member "id"
that is used to set the name of kernel thread is totally random.

Some board drivers (for example cx88-dvb) set this "id" via
videobuf_dvb_alloc_frontend but most do not.

So I at least get random id values for saa7134, flexcop and ttpci based cards.
It looks like this in dmesg:
DVB: registering adapter 1 frontend -10551321 (ST STV0299 DVB-S)

The related kernel thread then also gets a strange name
like "kdvb-ad-1-fe--1".

Subject: siano: read buffer overflow

From: Roel Kluin <roel.kluin@gmail.com>

With mode DEVICE_MODE_RAW_TUNER a read occurs past the end of smscore_fw_lkup[].
Subsequently an attempt is made to load the firmware from the resulting
filename.

Subject: fix device match logic

From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

I forgot to change USB_DEVICE_ID_MATCH_VENDOR to USB_DEVICE_ID_MATCH_DEVICE in
the last commit, defeating its whole purpose. Fix this.
