Merge tag 'drm-misc-next-2024-04-25' of https://gitlab.freedesktop.org/drm/misc/kernel into drm-next

drm-misc-next for v6.10-rc1:

UAPI Changes:

Cross-subsystem Changes:
- Devicetree updates for rockchip (#sound-dai-cells)
- Add dt bindings for new panels.
- Change bridge/tc358775 dt bindings.

Core Changes:
- Fix SIZE_HINTS cursor property doc.
- Parse topology blocks for all DispID < 2.0.
- Implement support for tracking cleared free memory, use it in amdgpu.
- Drop seq_file.h from drm_print.h, and include debugfs.h explicitly
where needed (drivers).

Driver Changes:
- Small fixes to rockchip, panthor, v3d, bridge chaining, xlx.
- Add Khadas TS050 V2, EDO RM69380 OLED, CSOT MNB601LS1-1 panels,
- Add SAM9X7 SoC's LVDS controller.
- More driver conversions to struct drm_edid.
- Support tc358765 in tc358775 bridge.
