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

/**
* DOC: CRC ABI
*
* DRM device drivers can provide to userspace CRC information of each frame as
* it reached a given hardware component (a "source").
*
* Userspace can control generation of CRCs in a given CRTC by writing to the
* file dri/0/crtc-N/crc/control in debugfs, with N being the index of the CRTC.
* Accepted values are source names (which are driver-specific) and the "auto"
* keyword, which will let the driver select a default source of frame CRCs
* for this CRTC.
*
* Once frame CRC generation is enabled, userspace can capture them by reading
* the dri/0/crtc-N/crc/data file. Each line in that file contains the frame
* number in the first field and then a number of unsigned integer fields
* containing the CRC data. Fields are separated by a single space and the number
* of CRC fields is source-specific.
*
* Note that though in some cases the CRC is computed in a specified way and on
* the frame contents as supplied by userspace (eDP 1.3), in general the CRC
* computation is performed in an unspecified way and on frame contents that have
* been already processed in also an unspecified way and thus userspace cannot
* rely on being able to generate matching CRC values for the frame contents that
* it submits. In this general case, the maximum userspace can do is to compare
* the reported CRCs of frames that should have the same contents.
