Merge tag 'drm-misc-next-2025-04-29' of https://gitlab.freedesktop.org/drm/misc/kernel into drm-next

drm-misc-next for v6.16-rc1:

UAPI Changes:
- panthor now fails in mmap_offset call for a BO created with
  DRM_PANTHOR_BO_NO_MMAP.
- Add DRM_PANTHOR_BO_SET_LABEL ioctl and label panthor kernel BOs.

Cross-subsystem Changes:
- Add kmap_local_page_try_from_panic for drm/panic.
- Add DT bindings for panels.
- Update DT bindings for imagination.
- Extend %p4cc in lib/vsprintf.c to support fourcc printing.

Core Changes:
- Remove the disgusting turds.
- Register definition updates for DP.
- DisplayID timing blocks refactor.
- Remove now unused mipi_dsi_dsc_write_seq.
- Convert panel drivers to not return error in prepare/enable and
  unprepare/disable calls.

Driver Changes:
- Assorted small fixes and featuers for rockchip, panthor, accel/ivpu,
  accel/amdxdna, hisilicon/hibmc, i915/backlight, sysfb, accel/qaic,
  udl, etnaviv, virtio, xlnx, panel/boe-bf060y8m-aj0, bridge/synopsis,
  panthor, panel/samsung/sofef00m, lontium/lt9611uxc, nouveau, panel/himax-hx8279,
  panfrost, st7571-i2c.
- Improve hibmc interrupt handling and add HPD support.
- Add NLT NL13676BC25-03F, Tianma TM070JDHG34-00, Himax HX8279/HX8279-D
  DDIC, Visionox G2647FB105, Sitronix ST7571 LCD Controller, panels.
- Add zpos, alpha and blend to renesas.
- Convert drivers to use drm_gem_is_imported, replacing gem->import_attach.
- Support TI AM68 GPU in imagination.
- Support panic handler in virtio.
- Add support to get the panel from DP AUX bus in rockchip and add
  RK3588 support.
- Make sofef00 only support the sofef00 panel, not another unrelated
  one.
- Add debugfs BO dumping support to panthor, and print associated labels.
- Implement heartbeat based hangcheck in ivpu.
- Mass convert drivers to devm_drm_bridge_alloc api.
