Remove soc_camera framework dependencies from mt9t112 sensor driver.
- Handle clk, gpios and power routines
- Register async subdev
- Remove deprecated g/s_mbus_config operations
- Remove driver flags
- Change driver interface and add kernel doc
- Adjust build system
- Fix code style issues reported by checkpatch in strict mode

This commit does not remove the original soc_camera based driver as long
as other platforms depends on soc_camera framework.

As I don't have access to a working camera module, this change has only
been compile tested.

This adds the same Kconfig dependency that we have in other

can call snd_pcm_hw_constraint_minmax, while depending on
CONFIG_SND_SOC for registering the codec.

data, but currently does not support any standard video interface
property.

Add support through OF parsing for 2 generic properties (vsync and hsync
polarities) and for one custom property already supported through
platform data to suppress pixel clock output during horizontal
blanking.

While at there, check return value of register writes in set_fmt
function and rationalize spacings.

The em28xx driver can use ov2640, but it doesn't depend
(or use) the GPIOLIB in order to power off/on the sensor.

So, as we want to allow both usages with and without

The Kconfig options for the CEC subsystem were a bit messy. In
addition there were two cec sources (cec-edid.c and cec-notifier.c)
that were outside of the media/cec directory, which was weird.

Move those sources to media/cec as well.

The cec-edid and cec-notifier functionality is now part of the cec
module and these are no longer separate modules.

Also remove the MEDIA_CEC_EDID config option and include it with the
main CEC config option (which defined CEC_EDID anyway).

Added static inlines to cec-edid.h for dummy functions when CEC_CORE
isn't defined.

CEC drivers should now depend on CEC_CORE.

CEC drivers that need the cec-notifier functionality must explicitly
select CEC_NOTIFIER.

The s5p-cec and stih-cec drivers depended on VIDEO_DEV instead of
CEC_CORE, fix that as well.
