Merge tag 'drm-msm-next-2021-04-11' of https://gitlab.freedesktop.org/drm/msm into drm-next

msm-next from Rob:
* Big DSI phy/pll cleanup. Includes some clk patches, acked by
  maintainer
* Initial support for sc7280
* compatibles fixes for sm8150/sm8250
* cleanups for all dpu gens to use same bandwidth scaling paths (\o/)
* various shrinker path lock contention optimizations
* unpin/swap support for GEM objects (disabled by default, enable with
  msm.enable_eviction=1 .. due to various combinations of iommu drivers
  with older gens I want to get more testing on hw I don't have in front
  of me before enabling by default)
* The usual assortment of misc fixes and cleanups
