Merge tag 'topic/drm-misc-2016-10-24' of git://anongit.freedesktop.org/drm-intel into drm-next

First -misc pull for 4.10:
- drm_format rework from Laurent
- reservation patches from Chris that missed 4.9.
- aspect ratio support in infoframe helpers and drm mode/edid code
  (Shashank Sharma)
- rotation rework from Ville (first parts at least)
- another attempt at the CRC debugfs interface from Tomeu
- piles and piles of misc patches all over
