Didn't have time for a detailed look yet, but at least one thing 
missing from your patch set is handling of possible_crtcs and
possible_clones for getplane and getencoder ioctls. AFAICT the
bits in those are supposed to tell you the index of the object ID
in the getresources reply. So when queried via a "render node",
some form of remapping must be performed.

Also the name "render node" is still very confusing. How about just
callling it a partition or something. Or maybe someone could suggest
a more self explanatory name for this stuff.
