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.

Generic FourCC code

-------------------



::

	%p4c[hnlb]	gP00 (0x67503030)



Print a generic FourCC code, as both ASCII characters and its numerical

value as hexadecimal.



The generic FourCC code is always printed in the big-endian format,

the most significant byte first. This is the opposite of V4L/DRM FourCCs.



The additional ``h``, ``n``, ``l``, and ``b`` specifiers define what

endianness is used to load the stored bytes. The data might be interpreted

using the host byte order, network byte order, little-endian, or big-endian.

description:

  The Himax HX8279 is a 1803 channel outputs source driver with MIPI

  TCON, which generates the horizontal and vertical control timing to

  the source and gate drivers.

  This DriverIC is most suitable for 1200x1920, 1080x1920, 1200x1600,

  and 600x1024 panels and outputs full RGB888 over two or four lanes,

  single or dual, MIPI-DSI video interface.
