Merge tag 'drm-next-2019-07-19' of git://anongit.freedesktop.org/drm/drm

Pull drm fixes from Daniel Vetter:
 "Dave is back in shape, but now family got it so I'm doing the pull.
  Two things worthy of note:

   - nouveau feature pull was way too late, Dave&me decided to not take
     that, so Ben spun up a pull with just the fixes.

   - after some chatting with the arm display maintainers we decided to
     change a bit how that's maintained, for more oversight/review and
     cross vendor collab.

  More details below:

  nouveau:
   - bugfixes
   - TU116 enabling (minor iteration) :w

  amdgpu:
   - large pile of fixes for new hw support this release (navi, vega20)
   - audio hotplug fix
   - bunch of corner cases and small fixes all over for amdgpu/kfd

  komeda:
   - back out some new properties (from this merge window) that needs
     more pondering.

  bochs:
   - fb pitch setup

  core:
   - a new panel quirk
   - misc fixes"
