Merge tag 'drm-misc-next-2020-09-21' of git://anongit.freedesktop.org/drm/drm-misc into drm-next

drm-misc-next for 5.10:

UAPI Changes:

Cross-subsystem Changes:
  - virtio: Merged a PR for patches that will affect drm/virtio

Core Changes:
  - dev: More devm_drm convertions and removal of drm_dev_init
  - atomic: Split out drm_atomic_helper_calc_timestamping_constants of
    drm_atomic_helper_update_legacy_modeset_state
  - ttm: More rework

Driver Changes:
  - i915: selftests improvements
  - panfrost: support for Amlogic SoC
  - vc4: one fix
  - tree-wide: conversions to devm_drm_dev_alloc,
  - ast: simplifications of the atomic modesetting code
  - panfrost: multiple fixes
  - vc4: multiple fixes
