Sure. Then the display controller could have more verbose description.
But the panel could still have what I wrote above, except the 'remote'
property would point to a real endpoint node inside the dispc node, not
to the dispc node.

This would, of course, need some extra code to handle the different
cases, but just from DT point of view, I think all the relevant
information is there.
