Merge tag 'drm-misc-next-2022-09-09' of git://anongit.freedesktop.org/drm/drm-misc into drm-next
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.

+description: |
+ MediaTek DP and eDP are different hardwares and there are some features
+ which are not supported for eDP. For example, audio is not supported for
+ eDP. Therefore, we need to use two different compatibles to describe them.
+ In addition, We just need to enable the power domain of DP, so the clock
+ of DP is generated by itself and we are not using other PLL to generate
+ clocks.

There's lots of plane features we could add support for:
-- Clearing primary plane: clear primary plane before plane composition (at the
- start) for correctness of pixel blend ops. It also guarantees alpha channel
- is cleared in the target buffer for stable crc. [Good to get started]
-
- ARGB format on primary plane: blend the primary plane into background with
translucent alpha.
-- Support when the primary plane isn't exactly matching the output size: blend
- the primary plane into the black background.
+- Add background color KMS property[Good to get started].
- Full alpha blending on all planes.
