[PATCH v3 00/10] Use media bus formats in imx-drm and add drm panel support

[Philipp Zabel]

Currently the imx-drm driver misuses the V4L2_PIX_FMT constants to describe the
pixel format on the parallel bus between display controllers and encoders. Now
that MEDIA_BUS_FMT is available, use that instead.

I'd like to get the V4L2 maintainers' acks for the four necessary media
bus format patches to be merged through the drm tree, if that still is the
preferred way for the media format patches to go in together with the driver
changes using them.

The two drm/imx core patches replace V4L2_PIX_FMT with MEDIA_BUS_FMT where
appropriate and consolidate the variable names for clarification.

The three LDB patches depend on the of-graph helper series:
    http://permalink.gmane.org/gmane.linux.kernel/1898485
They allow to optionally use LVDS panels with drm_panel drivers, connected to
the LDB encoder in the device tree via of-graph endpoint links.

Changes since v2:
 - Added explanation for component-wise padded format names (CPADHI/LO)
 - Improved documentation (wording, spelling and syntax fixes)
 - Also rename pixel_fmt parameter to ipu_dc_init_sync to bus_format
(- Added linux-media to Cc for the media format patches)
