drm-misc-next for v6.19:

UAPI Changes:

Cross-subsystem Changes:
-  fbcon cleanups.
- Make drivers depend on FB_TILEBLITTING instead of selecting it,
  and hide FB_MODE_HELPERS.

Core Changes:
- More preparations for rust.
- Throttle dirty worker with vblank
- Use drm_for_each_bridge_in_chain_scoped in drm's bridge code and
  assorted fixes.
- Ensure drm_client_modeset tests are enabled in UML.
- Rename ttm_bo_put to ttm_bo_fini, as a further step in removing the
  TTM bo refcount.
- Add POST_LT_ADJ_REQ training sequence.
- Show list of removed but still allocated bridges.
- Add a simulated vblank interrupt for hardware without it,
  and add some helpers to use them in vkms and hypervdrm.

Driver Changes:
- Assorted small fixes, cleanups and updates to host1x, tegra,
  panthor,   amdxdna, gud, vc4, ssd130x, ivpu, panfrost, panthor,
  sysfb, bridge/sn65dsi86, solomon, ast, tidss.
- Convert drivers from using .round_rate() to .determine_rate()
- Add support for KD116N3730A07/A12, chromebook mt8189, JT101TM023,
  LQ079L1SX01, raspberrypi 5" panels.
- Improve reclocking on tegra186+ with nouveau.
- Improve runtime pm in amdxdna.
- Add support for HTX_PAI in imx.
- Use a helper to calculate dumb buffer sizes in most drivers.
