Hi David,

I've rebased this on top of you drm-next branch as you requested. The
change in hdmi.c looks a bit odd, but that's due to the fact that the
nvidia,tegra30-hdmi line was already part of a prior patch where it
shouldn't have been introduced yet. This patch merely adjusts its
sorting order as currently required by the OF code.

Thierry
