Merge tag 'topic/drm-misc-2016-06-15' of git://anongit.freedesktop.org/drm-intel into drm-next

- best_encoder cleanup from Boris.
- drm_simple_display_pipe helpers from Noralf. Looks really neat imo, and
  there's 2-3 in-flight drivers which look like they could/should use it.
  Anyway, with this we have now helpers and everything in place to write
  drivers for simple hw with fewer complexity in the driver than what
  fbdev would need. That was the last complaint I've heard from embedded
  folks after we made atomic happen. Mission accomplished!
- nonblocking commit helpers for atomic, plus a bunch of driver patches
  for that.
- Prep patch from Laurent for cleaned up pixel format functions.
- More of Gustavo's cleanup for drm vblank functions.
- and a few oddball things in between

Plus the merge of docs-next to prep the docbook->sphinx conversion as
discussed. Jon cc'ed as fyi.
