Subject: pvrusb2: Split i2c module handling from i2c adapter

From: Mike Isely <isely@pobox.com>

This is the first step in the effort to move the pvrusb2 driver over
to using the v4l2-subdev framework.  This commit involves mainly
splitting apart pvrusb2-i2c-core - part of it is the driver's I2C
adapter driver and the rest is the old i2c module handling logic.  The
i2c module handling junk is moved out to pvrusb2-i2c-track and various
header references are correspondingly updated.  Yes, this patch has a
huge pile of checkpatch complaints, but I'm NOT going to fix any of
it.  Why?  First, I'm moving a large chunk of existing code and I'm
not going to spend time adjusting it to match someone's idea of coding
style.  Second, in the end I expect all that moved code to go away by
the time the rework is done so wasting time on it now to adhere to the
standard is in the end a large waste of time.

Priority: normal

Subject: pvrusb2: Set up v4l2_device instance

From: Mike Isely <isely@pobox.com>

Define a v4l2_device instance in the pvrusb2 driver and initialize /
tear it down appropriately.  This is a step in the v4l2-subdev
adoption effort.

Priority: normal

Subject: pvrusb2: Changes to further isolate old i2c layer

From: Mike Isely <isely@pobox.com>

This introduces some additional isolation in the pvrusb2 from the old
i2c layer, a step along the way to separate the driver from that layer
and to make it easier to introduce the common v4l2-subdev framework as
the eventual replacement.

Subject: pvrusb2: New device attribute mechanism to specify sub-devices

From: Mike Isely <isely@pobox.com>

Set up new mechanism for declaring and loading appropriate sub-devices
when driver initializes.  This is another part of the v4l2-subdev
adoption.

Subject: pvrusb2: Providing means to stop tracking an old i2c module

From: Mike Isely <isely@pobox.com>

This implements a temporary mechanism to "untrack" an i2c module from
the old i2c layer.  The v4l2-subdev related code in the driver will
use this to remove a sub-device from the old i2c layer.  In the end,
once the old i2c layer is removed, this will also eventually go away.

Priority: normal

Subject: pvrusb2: Set i2c autoprobing to be off by default

From: Mike Isely <isely@pobox.com>

In order to keep a sub-device from promiscuously attaching to the
pvrusb2 driver, the i2c adapter's class must be cleared.  This change
clears that class by default.

Tie up loose ends with v4l2-subdev setup.  Set attached module's group
ID to match our internal ID, emit a few useful messages when
sub-devices are dealt with, implement better error legs, and fix an
error in the old i2c layer (caused by changes related to the
v4l2-subdev work here).

Subject: pvrusb2: Note who our video decoder sub-device is, and set it up

From: Mike Isely <isely@pobox.com>

Other code may need to treat the video decoder sub-device in a special
manner, so this change implements code to recognize when such a
sub-device is connected to the driver, does any special processing for
it, and notes who the device is for future reference.

Subject: pvrusb2: Implement reporting of connected sub-devices

From: Mike Isely <isely@pobox.com>

The pvrusb2 driver has a function that reports internal state.  It can
be accessed from either the debug interface or as the result of a v4l
log status request.  This change adds information listing sub-devices
to the report.

Subject: pvrusb2: Implement sub-device specific update framework

From: Mike Isely <isely@pobox.com>

Lay down a foundation whereby it becomes possible to send customized
updates to specific sub-devices.  (This becomes useful for routing
configuration, which is a very sub-device specific operation.)

Subject: pvrusb2: Make audio sample rate update into a sub-device broadcast

From: Mike Isely <isely@pobox.com>

The pvrusb2 driver had previously been using i2c module specific calls
to set the sample rate (a long long time ago this was needed).  These
days it is safe to use a broadcast so let's just broadcast this when
communicating audio sample rate to sub-devices.

Priority: normal

Subject: pvrusb2: Allow sub-devices to insert correctly

From: Mike Isely <isely@pobox.com>

A sub-device won't successfully attach to our I2C adapter if its class
isn't set to zero.  Right the class is still set to
I2C_CLASS_TV_ANALOG in order to allow the old mechanism to still
work.  This change temporarily sets the class to zero during the
interval when the sub-device attaches.  This code will get removed
when the old i2c layer is finally removed from the driver.

Subject: pvrusb2: Sub-device update must happen BEFORE state dirty bits are
 cleared

From: Mike Isely <isely@pobox.com>

The sub-device update mechanism relies on various "dirty" bits in the
driver in order to know what pieces of state need to be propagated out
to the various sub-devices.  But that won't work if the dirty bits are
cleared before the update gets a chance to run.  This change ensures
that the update takes place before the dirty bits are cleared.

Subject: pvrusb2: Implement mechanism to force a full sub-device update

From: Mike Isely <isely@pobox.com>

When a pvrusb2 driver instance first initializes, we need to be sure
to send out a complete state update for everything to all attached
modules.  The old i2c layer did this by keeping a separate mask of
"stale" bits for each attached module - and setting that mask to all
stale when that module attaches.  But the new sub-device adaptation
I've implemented here no longer has per-module stale bits.  So instead
there's now a global "force dirty" bit that is set upon instance
initialization, before the sub-devices are attached.  After the first
update, this bit is cleared, allowing for normal update-on-dirty
behavior.  In this manner, we ensure that all sub-devices have been
properly synchronized at initialization.

Subject: pvrusb2: Issue required core init broadcast to all sub-devices

From: Mike Isely <isely@pobox.com>

The v4l2-subdev infrastructure requires that an initialization call
must be issued to all attached sub-devices before normal operation can
start.  This change satisfies that requirement.

Priority: normal

Subject: pvrusb2: Remove old i2c layer; we use v4l2-subdev now

From: Mike Isely <isely@pobox.com>

This change removes the old i2c module controlling layer from the
pvrusb2 driver.  This is code that first had appeared in the driver
back in December 2005.  It's history.  Now we use v4l2-subdev.  Please
note also that with this change, the driver will no longer be usable
in kernels older that 2.6.22.

Subject: pvrusb2: Remove ancient IVTV specific ioctl functions

From: Mike Isely <isely@pobox.com>

Remove ancient IVTV_IOC_G_CODEC and IVTV_IOC_S_CODEC ioctl functions
from the pvrusb2 driver.  These are very very old, were non-standard,
and were only present to keep MythTV happy (their implementation did
nothing except to report success).  That was long ago; no recent
versions of MythTV should require this anymore.

Subject: pvrusb2: Add sub-device for demod

From: Mike Isely <isely@pobox.com>

Forgot to include the tda9887 component when moving to v4l2-subdev.  I
got fooled because its name is "tuner", the same as the tuner module.
Silly me.

Subject: gspca - sq905c: New subdriver.

From: Theodore Kilgore <kilgota@auburn.edu>

The code in the new sq905c.c is based upon the structure of the code in
gspca/sq905.c, and upon the code in libgphoto2/camlibs/digigr8, which supports
the same set of cameras in stillcam mode. I am a co-author of gspca/sq905.c and
I am the sole author of libgphoto2/camlibs/digigr8, which is licensed under the
LGPL. I hereby give myself permission to use my own code from libgphoto2 in
gspca/sq905c.c.

Subject: gspca - sonixj: Prefer sonixj instead of sn9c102 for 0471:0327.

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

Prefer the gspca sonixj driver for the Philips SPC600NC webcam instead of
the sn9c102 driver. As we've got userreports that it works with the gspca
driver, whereas it fails with the sn9c102 driver, see:
https://bugzilla.redhat.com/show_bug.cgi?id=477111

Subject: hdpvr: locking fixes

From: Janne Grunau <j@jannau.net>

unlock io_mutex in hdpvr_stop_streaming hdpvr_disconnect to allow the
streaming worker to stop before we flush the workqueue.
do not return to user space with mutex held in vidioc_encoder_cmd with
an unknown encoder command.

Priority: normal
