- 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.
