b14667f32a V4L/DVB (11080): au0828: Convert to use v4l2_device/subdev framework
Convert over to using the new subdev framework for the au0828 bridge.  This
includes using the new i2c probing mechanism.

2eaf396020 V4L/DVB (11079): au0828: fix panic on disconnect if analog initialization failed
If the analog initialization failed to create the video device, we never
actually add the entry to the au0828_devlist.  Therefore a panic occurs when
unregistering the analog subsystem.

Make it so we only remove the entry from the list if we added it to the list
in the first place.

220be77c6e V4L/DVB (11078): au0828: properly handle non-existent analog inputs
It is not valid to look for dev->board.input == NULL to detect an undefined
analog configuration section, since it is a member of the struct and not a
pointer (hence it will *always* be non-NULL).  Do the check based on whether
the first input is actually a valid input type instead.

fc4ce6cd98 V4L/DVB (11077): au0828: properly handle missing analog USB endpoint
Move the setup of the analog isoc handler into au0828-video.c, so it does not
occur if there is not an .input section defined for the board.  Also fixes a
case where if there is an input section but the board does not actually have
analog support, the digital support will continue to work as expected.

dc8685b565 V4L/DVB (11074): au0828: fix i2c enumeration bug
There was a bug where enumerating the i2c for devices would result in false
positives.  The root of the issue was the scanning was using SMBUS_QUICK
messages, which are zero length write requests (which our i2c adapter
implementation didn't handle).  Because we never strobed any bytes onto the
bus, the status register would still contain the value from the previous
request.

32c000ad93 V4L/DVB (11067): au0828: workaround a bug in the au0828 i2c handling
There is an issue related to the i2c clock for addressing the xc5000.  The
au0828 chip does not support clock stretching, which the xc5000 makes use of.
This results in cases where we silently get back garbage in i2c read
operations.  To work around this issue until we slow down the i2c clock when
talking with that specific device.

This was not an issue before we had analog support because we never needed to
enumerate the i2c bus, and digital tuning never actually needed to perform
read operations against the xc5000.

patch moves negotiating of available host-camera format translations to
probe() time, and restores the state from the last close() on the next
open(). This is needed for some drivers, which power down or reset
hardware after the last user closes the interface. This patch also has a
nice side-effect of avoiding multiple allocation anf freeing of format

Normally the parent device of v4l2_device is used as the video device

video_device struct.

This is needed in the cx88 driver, which has one core v4l2_device but
creates multiple pci devices (one each for raw and mpeg video).

So you cannot associate the core v4l2_device with a particular PCI device,
but you can do that for each video_device.

cbb72b0f69 V4L/DVB (10947): Auto-load videodev module when device opened.
The videodev module is missing the char-major-81-* alias that would
cause it to be auto-loaded when a device of that type is opened.  This
patch adds the alias.

When unloading the cx8800 driver I sometimes get a general protection
fault. Analysis revealed a race in cx88_ir_stop(). It can be solved by
using a delayed work instead of a timer for infrared input polling.
