Anatolij,

I know this patch is old, but I'm now getting back to working on the
DIU driver.  One question I have: why are you reading the EDID data
from the device tree?  Why not just read it directly from the device
using I2C?  Who is supposed to put the EDID data into the device tree
in the first place?
