I haven't looked at this series yet, but all the omap display DT
bindings have been designed to be correct, and while omapdrm will
receive lots of changes, I don't see any need to touch anything in the
DT side.

Of course, if we will be using some existing common driver which
implements bindings in some other way, it'll cause some complexities...
