This way to using up one bit for each type sucks big time. IIRC we
discussed this at Fosdem and one idea was to leave the current bits as
sort of base types, and reserve a bunch of the other bits to indicate a
sub-type. For instance the new signed range and object ID prop types
could be sub-types of the current range type.
Maybe we should reserve a few more bits for new base types in case we
need them in the future, or just add sometime king DRM_MODE_PROP_MISC,
which is where we'd stick every sub-type that doesn't fit the current
base types.
