Pull drm updates from Dave Airlie:
 "This is the main drm pull request for 5.7-rc1.

  Highlights:

   - i915 enables Tigerlake by default

   - i915 and amdgpu have initial OLED backlight support

     [ Jani Nikula pipes up and points out that we've had a bunch of
       "initial support" code for a long time already, but only now
       Lyude made it actually work on real world machines ]

   - vmwgfx add support to enable OpenGL 4 userspace

   - zero length arrays are mostly removed.

  Detailed summary:

   - rework drm_global_mutex
   - bridge rework to allow omap_dss custom driver removeal
   - remove drm_fb_helper connector interrfaces
   - zero-length array removal

   - support for modifying the sched list
   - revert job distribution optimization
   - helper to pick least loaded scheduler
   - race condition fix

  mst:
   - various fixes
