Hello,

This patch set adds support for the HDMI output port present on the Renesas
Koelsch board. Doing so requires two components, a driver for the external
ADV7511W HDMI encoder, and support for HDMI encoders in the DU driver.

The HDMI encoder drivers uses the DRM slave encoder framework and the
component framework to communicate with the DU driver. The DT bindings are
based on the OF graph bindings to link the display controller and encoder.

The first two patches have been taken from Philipp Zabel's "[PATCH v3 0/8]
Add of-graph helpers to loop over endpoints and find ports by id" series.
Philipp, I don't see that series in linux-next, what's the merge status ?

The R-Car DU patches start with a bit of refactoring, to finally add HDMI
support in patch 08/12.

The new adv7511 driver (patch 11/12) depends on decoupling EDID parsing from
the DDC I2C adapter (patch 09/12). It supports DT instantiation only (bindings
are documented in patch 10/12) for now. Platform data support could be added
later if needed. The code is based on Lars-Peter Clausen's adv7511 driver,
with heavy modifications.

The last patch instantiates the HDMI encoder in the Koelsch board DT file and
connects it to the DU output.

The patch series depends on Koelsch DU DT enablement (scheduled for merge in
v3.19-rc1). Dave, I'd like to get this merged in v3.19-rc1, how would you like
to proceed ? Could it go through Simon's Renesas tree ? There's a small risk
of conflict in drivers/gpu/drm/drm_edid.c, include/drm/drm_edid.h,
drivers/gpu/drm/i2c/Kconfig and drivers/gpu/drm/i2c/Makefile. Simon, could you
alternatively provide a stable branch with the required dependencies ?

Changes since v1:

- Dropped Philipp Zabel's OF graph patches (the rcar-du-drm driver will be
  udpated to use for_each_endpoint_of_node when the implementation hits
  upstream)
- adv7511: Clarify the adi,input-format DT property documentation
- adv7511: Use map array to convert input style to hardware value
- adv7511: Fixed typos

For ease of testing and review I've pushed this series and its dependencies to
a git branch on
