b0d3159be9 V4L/DVB (11901): v4l2: Create helper function for bounding and aligning images
Most hardware has limits on minimum and maximum image dimensions and also
requirements about alignment.  For example, image width must be even or a
multiple of four.  Some hardware has requirements that the total image size
(width * height) be a multiple of some power of two.

v4l_bound_align_image() will enforce min and max width and height, power of
two alignment on width and height, and power of two alignment on total
image size.

It uses an efficient algorithm that will try to find the "closest" image
size that meets the requirements.

f0222c7d86 V4L/DVB (12125): v4l2: add new s_config subdev ops and v4l2_i2c_new_subdev_cfg/board calls
Add a new s_config core ops call: this is called with the irq and platform
data to be used to initialize the subdev.

Added new v4l2_i2c_new_subdev_cfg and v4l2_i2c_new_subdev_board calls
that allows you to pass these new arguments.

The existing v4l2_i2c_new_subdev functions were modified to also call
s_config.

In the future the existing v4l2_i2c_new_subdev functions will be replaced
by a single v4l2_i2c_new_subdev function similar to v4l2_i2c_new_subdev_cfg
but without the irq and platform_data arguments.

Make it very clear that this header should not be used for i2c drivers that
do not need to be compiled for pre-2.6.26 kernels.

As soon as the minimum supported kernel in the v4l-dvb repository becomes

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.

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.

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.

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
translation tables.

The removal of the timer which polls the infrared input is racy.
Replacing the timer with a delayed work solves the problem.

51f0b8d57a V4L/DVB (10813): v4l2: New function v4l2_video_std_frame_period
Some code was calling v4l2_video_std_construct() when all it cared about
was the frame period.  So make a function that just returns that and have
v4l2_video_std_construct() use it.

At this point there are no users of v4l2_video_std_construct() left outside
of v4l2-ioctl, so it could be un-exported and made static.

Change v4l2_video_std_construct() so that it doesn't zero out the struct
v4l2_standard passed in.  It's already been zeroed out in the common ioctl
code.
