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
