fccea74ff8 [media] Kconfig: merge all customise options into just one
Instead of having 3 options to allow customizing the media
sub-drivers (tuners, I2C drivers, frontends), merge all of
them into just one.

That simplifies the life for users, as they can just keep
this untouched.

Life for developers is also simpler, as there's now just
one Kconfig item to remember, for the ancillary sub-drivers
providing supports for chips that could change from one
board design to another.

b6334460f2 [media] Cleanup media Kconfig files
- get rid of ridden V4L2_COMMON symbol

  This symbol is not needed anymore; it can be folded with V4L2
  one, simplifying the Kconfig a little bit;

- Comment why some Kconfig items are needed;

- Remove if test for MEDIA_CAMERA_SUPPORT, replacing it by
  depends on.

c078ac18f3 [media] mt9v022: Add support for mt9v024
Driver for mt9v022 camera sensor is fully compatible for mt9v024 camera sensor
with the exception of several registers which have been changed addresses.
mt9v024 also has improved and additional features, but they are currently not in use.

ca9ef7fa21 [media] ov772x: Select the default format at probe time
The format and window size are only initialized during the first g_fmt
call. This leaves the device in an inconsistent state after
initialization, which will cause problems when implementing pad
operations. Move the format and window size initialization to probe
time.

4bbc6d52e6 [media] soc-camera: Push probe-time power management to drivers
Several client drivers access the hardware at probe time, for instance
to read the probe chip ID. Such chips need to be powered up when being
probed.

soc-camera handles this by powering chips up in the soc-camera probe
implementation. However, this will break with non soc-camera hosts that
don't perform the same operations.

Fix the problem by pushing the power up/down from the soc-camera core
down to individual drivers on a needs basis.

4ec10bacd6 [media] soc-camera: Add and use soc_camera_power_[on|off]() helper functions
Instead of forcing all soc-camera drivers to go through the mid-layer to
handle power management, create soc_camera_power_[on|off]() functions
that can be called from the subdev .s_power() operation to manage
regulators and platform-specific power handling. This allows non
soc-camera hosts to use soc-camera-aware clients.
