Merge tag 'drm-fixes-v4.7-rc1' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie:
- one IMX built-in regression fix
- a set of amdgpu fixes, mostly powerplay and polaris GPU stuff
- a set of i915 fixes all over, many cc'ed to stable.
The i915 batch contain support for DP++ dongle detection, which is
used to fix some regressions in the HDMI color depth area
