Merge branch 'drm/du/adv7511' of git://linuxtv.org/pinchartl/fbdev into drm-next

Merge branch 'drm/du/adv7511' of git://linuxtv.org/pinchartl/fbdev into drm-next

The branch is based on a merge of drm-next and Simon's tags/renesas-dt-du-for-
v3.19 available at
git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git, the latter
having been pulled in the ARM SoC tree for v3.19.

Compared to v1, I've rebased my branch on a later drm-next, added Julia's
error return code fix, and documented the "drm: Decouple EDID parsing from I2C
adapter" patch properly.

v1:
Here's a pull request that adds HDMI support to the R-Car DU driver, including
a new slave encoder driver for the adv7511.
