- bridge cleanup refactor (Benjamin Gaignard)

Core Changes:
- less surprising atomic iterators (Maarten), fixes an oops introduced
  in drm-next
- better gem/fb helper docs (Noralf)
- fix dma-buf rcu races (Christian König)

Driver Changes:
- adv7511: CEC support (Hans Verkuil)
- sun4i update from Chen-Yu to improve hdmi and A31 support
- sii8620: add remote control support (Maceiej Purski)

New drivers:
- SiI9234 bridge driver (Maciej Purski)
- 7" rpi touch panel (Eric Anholt)

Note that this contains a topic pull from regmap, needed by the sun4i
changes. Mark Brown sent that out for pulling into drm-misc.
