Merge tag 'topic/drm-misc-2015-03-10' of git://anongit.freedesktop.org/drm-intel into drm-next

Another pile of misc drm patches all over, mostly polish for atomic. Last
minute rebase was to avoid the broken merge.

* tag 'topic/drm-misc-2015-03-10' of git://anongit.freedesktop.org/drm-intel:
  drm: Check in setcrtc if the primary plane supports the fb pixel format
  drm: Lighten sysfs connector 'status'
  drm/plane-helper: unexport drm_primary_helper_create_plane
  drm: Share plane pixel format check code between legacy and atomic
  drm: Fix trivial typos in comments
  drm/dp: add DPCD definitions from eDP 1.4
  drm/dp: add DPCD definitions from DP 1.1 and 1.2a
  drm: Fixup racy refcounting in plane_force_disable
  drm/i915: Rotation property is now handled in DRM core
  drm: Complete moving rotation property to core
  drm/dp: add DPCD definitions from eDP 1.2
  drm/dp: indentation and ordering cleanups
  drm/atomic-helper: Fix kerneldoc for prepare_planes
  drm: Remove redundant code in the getencoder ioctl
