Merge tag 'drm-for-v4.15-part2' of git://people.freedesktop.org/~airlied/linux

Pull more drm updates from Dave Airlie:
 "Fixes/cleanups for rc1, non-desktop flags for VR

   - remove the MSM dt-bindings file Rob managed to push in the previous
     pull.

   - add a property/edid quirk to denote HMD devices, I had these
     hanging around for a few weeks and Keith had done some work on
     them, they are fairly self contained and small, and only affect
     people using HTC Vive VR headsets so far.

   - amdgpu, tegra, tilcdc, fsl fixes

   - some imx-drm cleanups I missed, these seemed pretty small, and no
     reason to hold off.

  I have one TTM regression fix (fixes bochs-vga in qemu) sitting
  locally awaiting review I'll probably send that in a separate pull
  request tomorrow"
