From: Ville Syrjälä <ville.syrj...@linux.intel.com>
On atomic drivers we can dig out the primary plane rotation from the
plane state instead of looking at the legacy crtc->invert_dimensions
flag. The flag is not set by anyone except omapdrm, and it would be
racy to set it the same way in the atomic helpers.
