Just a quick clarification: My ack was only about the drm driver itself, I
try really hard to stay away from DT insanity ;-) So please drop my ack
from these two patches.

Aside: DT patches need to go through a special process and you must cc dt
maintainers and mailing lists. Your patch seems to lack this, which afaiui
is a blocker for merging the driver.

Thanks, Daniel
Oh, I'm sorry, I will drop it soon.
