Merge branch 'drm-sti-next-atomic-2015-08-11' of http://git.linaro.org/people/benjamin.gaignard/kernel into drm-next

This serie of patches fix minor bugs around how driver sub-components are
bind and planes z-ordering.
The main part is about atomic support: using more atomic helpers allow us
to simplify the code (~300 lines removed) and to ahve a better match between
drm concepts (planes and crtc) and hardware split.

[airlied: fixed up conflict in atomic code]

* 'drm-sti-next-atomic-2015-08-11' of http://git.linaro.org/people/benjamin.gaignard/kernel:
  drm/sti: atomic crtc/plane update
  drm/sti: rename files and functions
  drm/sti: code clean up
  drm/sti: fix dynamic z-ordering
  drm: sti: fix sub-components bind
