Yes, our DSS have similar flexibility. That is, we don't have a special
fullscreen framebuffer for the crtc. Instead we have generic "overlays"
for all framebuffers that can be positioned anywhere and have any
format, all on a background color of choice. So we are happy with a more
generic approach where current implementation use a default plane for
crtc fb. But it should not hog HW resources when not used. If a plane is
used, I think it should be a "normal" plane that the user can control
and enumerate.
