drm-misc-next for v5.9:

UAPI Changes:

Cross-subsystem Changes:
- Add ckoenig as dma-buf maintainer.
- Revert invalid fix for dma-fence-chain, and fix selftest.
- Add fixmes to amifb about APUS support.
- Use array3_size in fbcon_prepare_logo, and struct_size() in alloc_apertures.
- Fix leaks in neofb, fb/savage and omapfb.
- Other small fixes to fb code.
- Convert some dt bindings to schema for some panels, and fix simple-framebuffer dt example.

Core Changes:
- Add DRM_FORMAT_MOD_GENERIC_16_16_TILE as alias to DRM_FORMAT_MOD_SAMSUNG_16_16_TILE,

- Refactor hisilicon's hibmc_drv_vdac.
- Create a TXP CRTC for vc4.
- Rework cursor support in ast.
- Fix runtime PM in STM.
- Allow bigger cursors in vkms.
- Cleanup sg handling in radeon and amdgpu, and stop creating dummy
  gtt nodes with ttm fixed.
- Rework crtc handling in mgag200.
- Miscellaneous small fixes to meson, vgem, bridge/dw-hdmi,
  panel/auo,b116xw03, panel/LG LB070WV8, lima, bridge/sil_sii8620,
