Merge tag 'drm-misc-next-2021-01-19' of git://anongit.freedesktop.org/drm/drm-misc into drm-next

drm-misc-next for v5.12:

UAPI Changes:
- Fix fourcc macro for amlogic video fbc.

Cross-subsystem Changes:
- Export pci_rebar_bytes_to_size.
- Add a PCI quirk to increase bar0 for RX 5600 XT Pulse to max possible size.
- Convert devicetree bindings to use the OF graph schema.
- Update s6e63m0 bindings.
- Make omapfb2 DSI_CM incompatible with drm/omap2 DSI-CM because of
  module conflicts.
- Add Zack Rusin as vmwgfx maintainer.
- Add CONFIG_DMABUF_DEBUG for validating dma-buf users don't loo kat struct page when importing or detaching.

Core Changes:
- Remove references to drm_device.pdev
- Fix regression in ttm_bo_move_to_lru_tail().
- Assorted docbook updates.
- Do not send dp-mst hotplug events on error when probing.
- Move some agp macros to agpsupport.c, so it's not always compiled.
- Move drm_need_swiotlb.h to drm_cache.c
- Only build drm_memory.o for legacy drivers, and move CONFIG_DRM_VM to legacy.
- Nuke drm_device.hose
- Warn when the ttm resource manager is non-empty when disabling.
- Assorted small fixes.

Driver Changes:
- Small assorted fixes in radeon, v3d, hisilicon, mipi-dbi, panfrost, hibmc, vc4, amdgpu, vkms, vmwgfx.
- Move hisilicon to use simple encode.
- Add writeback connector to vkms.
- Add support for BT2020 to DE3.
- Use gem prime mmap helpers in vc4, and move the mmap function upwards.
- Use managed drm device, and cleanup error paths and display registers in vmwgfx.
- Use correct bus_format and connector_type for innolux_n116bge.
- Fix a lot of warnings with W=1 (Lee Jones)
