Pull drm fixes from Dave Airlie:
 "Pre-LCA pull request I'm not sure how things will look next week,
  myself and Daniel are at LCA and I'm speaking quite late, so if I get
  my talk finished I'll probably process fixes.

  This week has a bunch of i915 fixes, some amdgpu fixes, one sun4i, one
  core MST, and one core fb_helper fix. More details below:

  core:
   - mst Fix NO_STOP_BIT bit offset (Wayne)

  fb_helper:
   - fb_helper: Fix bits_per_pixel param set behavior to round up
     (Geert)

  sun4i:
   - Fix RGB_DIV clock min divider on old hardware (Chen-Yu)

  amdgpu:
   - Stability fix for raven
   - Reduce pixel encoding to if max clock is exceeded on HDMI to allow
     additional high res modes
   - enable DRIVER_SYNCOBJ_TIMELINE for amdgpu

  i915:
   - Fix GitLab issue #446 causing GPU hangs: Do not restore invalid RS
     state
   - Fix GitLab issue #846: Restore coarse power gating that was
     disabled by initial RC66 context corruption security fixes.
   - Revert f6ec9483091f ("drm/i915: extend audio CDCLK>=2*BCLK
     constraint to more platforms") to avoid screen flicker
   - Fix to fill in unitialized uabi_instance in virtual engine uAPI
   - Add two missing W/As for ICL and EHL"
