Merge tag 'topic/drm-misc-2016-10-05' of git://anongit.freedesktop.org/drm-intel into drm-next

Another attempt, this time rebased and without the pipe crc patches:
- display_info cleanups from Ville
- make prime/gem lookups faster with rbtrees (Chris)
- misc stuff all over

* tag 'topic/drm-misc-2016-10-05' of git://anongit.freedesktop.org/drm-intel:
  drm/rockchip: analogix_dp: Refuse to enable PSR if panel doesn't support it
  drm/bridge: analogix_dp: Add analogix_dp_psr_supported
  drm/fb-helper: add DRM_FB_HELPER_DEFAULT_OPS for fb_ops
  drm: Document caveats around atomic event handling
