next version will be 'tilcdc' :-)

I would appreciate some thoughts about more generic devicetree lcd
panel parameters for the (ti)lcdc_panel patch.. from a functional
standpoint, I think the lcd panel support part is also pretty much
ready to go (I've added backlight support since the last version I
sent), but I'm not really happy with the DT bindings for that because
they seem to me a bit too hw specific, but I'm not really sure how
they should look.

Fwiw, on the CDF <-> KMS end of things, I'm sort of thinking the i2c
encoder slave is not too far off.. just needs to be a bit decoupled
from i2c.
