Merge branch 'drm-sti-next-2014-12-11' of http://git.linaro.org/people/benjamin.gaignard/kernel into drm-next

This series of patches fix various issues in STI drm driver.
Now HDMI i2c adapter could be selected in device tree
and plug detection doesn't use gpio anymore.
I also had fix some signal timing problems after testing the driver
on more hardware.
The remaining patches attemps to simplify the code and prepare
the next evolutions like DVO and auxiliary CRTC support

* 'drm-sti-next-2014-12-11' of http://git.linaro.org/people/benjamin.gaignard/kernel:
  drm: sti: correctly cleanup CRTC and planes
  drm: sti: add HQVDP plane
  drm: sti: add cursor plane
  drm: sti: enable auxiliary CRTC
  drm: sti: fix delay in VTG programming
  drm: sti: prepare sti_tvout to support auxiliary crtc
  drm: sti: use drm_crtc_vblank_{on/off} instead of drm_vblank_{on/off}
  drm: sti: fix hdmi avi infoframe
  drm: sti: remove event lock while disabling vblank
  drm: sti: simplify gdp code
  drm: sti: clear all mixer control
  drm: sti: remove gpio for HDMI hot plug detection
  drm: sti: allow to change hdmi ddc i2c adapter
