Merge tag 'drm-fixes-2020-11-06-1' of git://anongit.freedesktop.org/drm/drm

Pull drm fixes from Dave Airlie:
 "It's Friday here so that means another installment of drm fixes to
  distract you from the counting process.

  Changes all over the place, the amdgpu changes contain support for a
  new GPU that is close to current one already in the tree (Green
  Sardine) so it shouldn't have much side effects.

  Otherwise imx has a few cleanup patches and fixes, amdgpu and i915
  have around the usual smattering of fixes, fonts got constified, and
  vc4/panfrost has some minor fixes. All in all a fairly regular rc3.

  We have an outstanding nouveau regression, but the author is looking
  into the fix, so should be here next week.

  I now return you to counting.

  fonts:
   - constify font structures.

  MAINTAINERS:
   - Fix path for amdgpu power management

  amdgpu:
   - Add support for more navi1x SKUs
   - Fix for suspend on CI dGPUs
   - VCN DPG fix for Picasso
   - Sienna Cichlid fixes
   - Polaris DPM fix
   - Add support for Green Sardine

  amdkfd:
   - Fix an allocation failure check

  i915:
   - Fix set domain's cache coherency
   - Fixes around breadcrumbs
   - Fix encoder lookup during PSR atomic
   - Hold onto an explicit ref to i915_vma_work.pinned
   - gvt: HWSP reset handling fix
   - gvt: flush workaround
   - gvt: vGPU context pin/unpin
   - gvt: mmio cmd access fix for bxt/apl

  imx:
   - drop unused functions and callbacks
   - reuse imx_drm_encoder_parse_of
   - spinlock rework
   - memory leak fix
   - minor cleanups

  vc4:
   - resource cleanup fix

  panfrost:
   - madvise/shrinker fix"
