Jean Delvare 4d7a2d6721 V4L/DVB (11845): ir-kbd-i2c: Use initialization data
For specific boards, pass initialization data to ir-kbd-i2c instead
of modifying the settings after the device is initialized. This is
more efficient and easier to read.

Jean Delvare c668f32dca V4L/DVB (11844): ir-kbd-i2c: Switch to the new-style device binding model
Let card drivers probe for IR receiver devices and instantiate them if
found. Ultimately it would be better if we could stop probing
completely, but I suspect this won't be possible for all card types.

There's certainly room for cleanups. For example, some drivers are
sharing I2C adapter IDs, so they also had to share the list of I2C
addresses being probed for an IR receiver. Now that each driver
explicitly says which addresses should be probed, maybe some addresses
can be dropped from some drivers.

Also, the special cases in saa7134-i2c should probably be handled on a
per-board basis. This would be more efficient and less risky than always
probing extra addresses on all boards. I'll give it a try later.

Jean Delvare 1df8e9861c V4L/DVB (11843): ir-kbd-i2c: Don't use i2c_client.name for our own needs
In the standard device driver binding model, the name field of
struct i2c_client is used to match devices to their drivers, so we
must stop using it for internal purposes. Define a separate field
in struct IR_i2c as a replacement, and use it.

Guennadi Liakhovetski 594bb46dbc V4L/DVB (11607): soc-camera: add a free_bus method to struct soc_camera_link
Currently pcm990 camera bus-width management functions request a GPIO and never
free it again. With this approach the GPIO extender driver cannot be unloaded
once camera drivers have been loaded, also unloading theb i2c-pxa bus driver
produces errors, because the GPIO extender driver cannot unregister properly.
Another problem is, that if camera drivers are once loaded before the GPIO
extender driver, the platform code marks the GPIO unavailable and only a reboot
helps to recover. Adding an explicit free_bus method and using it in mt9m001
and mt9v022 drivers fixes these problems.

Hans Verkuil acebc70d4a V4L/DVB (11372): v4l2: use old-style i2c API for kernels < 2.6.26 instead of < 2.6.22
Originally the intention was to switch to the new style i2c API starting with
the introduction of the API in 2.6.22. However, the i2c_new_probed_device()
function has a lethal bug that wasn't fixed until 2.6.25. Or more accurately,
it was only fixed in the stable series of 2.6.25 and 2.6.26.

Given the fact that the new i2c API also changed starting with 2.6.26 (the
addition of i2c_device_id), it is easiest to switch APIs starting with
2.6.26.

This patch updates all the legacy code accordingly.
