Hi Tomi,
Thank you for the patch.

Should you in that case drop the panel-dpi compatible string too, as the
panel-dpi bindings require panel timings in DT ?
Yeah sounds like if panel-dpi is no longer usable for this device it
should be dropped from the compatible list.
Ok, I agree.
Looking at the dts files, panel-dpi is used in a bunch of boards. But
we even have 3 dts files with panel-dpi, without the detailed panel
model in compatible...
Fixing those will break the compatibility with old dtbs and new
kernel, unless we add timings-from-dt to a panel driver that handles
panel-dpi.
I know, and I don't have a perfect answer for this :-( I don't see a
third option, it's either breaking DT backward compatibility or adding
timings parsing to a panel driver (either a new panel-dpi driver or to
panel-simple). What's your preferred option ?
Hmm, I just realized that changing these will break omapfb. It relies on panel-dpi and timings from
DT...
