Merge tag 'drm-msm-next-2020-09-27' of https://gitlab.freedesktop.org/drm/msm into...

* DSI support for sm8150/sm8250
* Support for per-process GPU pagetables (finally!) for a6xx.
  There are still some iommu/arm-smmu changes required to
  enable, without which it will fallback to the current single
  pgtable state.  The first part (ie. what doesn't depend on
  drm side patches) is queued up for v5.10[1].
* DisplayPort support.  Userspace DP compliance tool support
  is already merged in IGT[2]
* The usual assortment of smaller fixes/cleanups
