[PATCH RFC v2 00/15] V4L2 device tree bindings and OF helpers

[Sylwester Nawrocki]

This series includes the updated DT bindings documentation and the V4L2 OF
parser. Changes since v1:

 - renamed 'link' nodes to 'endpoint', remote phandle to 'remote-endpoint'
   in the common bindings documentation file,
 - removed references to V4L2 in the documentation,
 - file v4l2.txt renamed to video-interfaces.txt,
 - dropped patches adding empty function definitions for when CONFIG_OF
   is disabled,
 - v4l2_of_parse_link() function renamed to v4l2_of_parse_endpoint,
 - created separate helpers to parse parallel and MIPI-CSI2 bus properties
   independently.

The bindings documentation patch is almost unchanged since version posted
on 12 Dec [1].

This series also includes patches adding device tree support for Exynos4
SoC camera subsystem drivers. Changes in that part include:

 - code refactoring to not depend on dummy function definitions,
 - updated to use new helpers from drivers/media/v4l2-core/v4l2-of.c,
 - added parsing of nodes corresponding to parallel video bus sensors.

My next steps include testing this on top of the common clock framework
patches for Exynos SoCs, posted recently by Thomas Abraham, and further
adding support for v4l2 asynchronous sub-device registration. However
I'd like to possibly have these patches in mainline first, only except
the "ARM: EXYNOS4: Add OF_DEV_AUXDATA for FIMC, FIMC-LITE and CSIS" one,
which won't be needed when there is common clock support available.

I appreciate any feedback, especially on the documentation and the OF
helpers.
