Merge tag 'drm-for-v4.16-part2-fixes' of git://people.freedesktop.org/~airlied/linux

Pull more drm updates from Dave Airlie:
 "Ben missed sending his nouveau tree, but he really didn't have much
  stuff in it:

   - GP108 acceleration support is enabled by "secure boot" support

   - some clockgating work on Kepler, and bunch of fixes

   - the bulk of the diff is regenerated firmware files, the change to
     them really isn't that large.

  Otherwise this contains regular Intel and AMDGPU fixes"
