drm-misc-next for v6.1-rc1:

[airlied - fix sun4i_tv build]

UAPI Changes:
- Hide unregistered connectors from GETCONNECTOR ioctl.
- drm/virtio no longer advertises LINEAR modifier, as it doesn't work.
-

Cross-subsystem Changes:
- Fix GPF in udmabuf failure path.

Core Changes:
- Rework TTM placement to use intersect/compatible functions.
- Drop legacy DP-MST support.
- More DP-MST related fixes, and move all state into atomic.
- Make DRM_MIPI_DBI select DRM_KMS_HELPER.
- Add audio_infoframe packing for DP.
- Add logging when some atomic check functions fail.
- Assorted documentation updates and fixes.

Driver Changes:
- Assorted cleanups and fixes in msm, lcdif, nouveau, virtio,
  panel/ilitek, bridge/icn6211, tve200, gma500, bridge/*, panfrost, via,
  bochs, qxl, sun4i.
- Add add AUO B133UAN02.1, IVO M133NW4J-R3, Innolux N120ACA-EA1 eDP panels.
- Improve DP-MST modeset state handling in amdgpu, nouveau, i915.
- Drop DP-MST from radeon driver, it was broken and only user of legacy
  DP-MST.
- Handle unplugging better in vc4.
- Simplify drm cmdparser tests.
- Add DP support to ti-sn65dsi86.
- Add MT8195 DP support to mediatek.
- Support RGB565, XRGB64, and ARGB64 formats in vkms.
- Convert sun4i tv support to atomic.
- Refactor vc4/vec TV Modesetting, and fix timings.
- Use atomic helpers instead of simple display helpers in ssd130x.

Maintainer changes:
- Add Douglas Anderson as reviewer for panel-edp.
