From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
I'd prefer have the crtc "rotation" property rotate the entire crtc
(planes and all). So for that reason we'd need to come up with some
other name for the "rotate the primary plane only" property.
Originally I had though that omapdrm had already made the decision for
us, but after another look, it looks like it never attaches the
"rotation" property to the crtc. So we can still change the name
without any ABI breakage.
Suggestions for better naming scheme are also welcome....
TODO: squash into "drm/i915: Add 180 degree primary plane rotation support"?
