What's left is the display-subsystem { } entity to describe the makeup of the subsystem. That's not included as we currently need to pass a block of memory, and the DT support for reserving chunks of memory appeared (last time I looked) to only be botch-merged (only half of it seems to have been merged making the whole reserved memory thing totally useless - why people only half-merge features I've no idea.)
There was a follow-up patch set for this some days ago http://comments.gmane.org/gmane.linux.ports.arm.kernel/337686
Yes, I did a bit of digging a while back and found the outstanding stuff, but it wasn't clear what's happening with it. As it isn't part of mainline, and I don't want to pick up further patches to add dependencies, I decided it was better to stick with old proven ways of a manually declared platform device for the time being.
