drm-misc-next for v6.12:

UAPI Changes:
- Add panthor/DEV_QUERY_TIMESTAMP_INFO query.

Cross-subsystem Changes:
- Updated dt bindings.
- Add documentation explaining default errnos for fences.
- Mark dma-buf heaps creation functions as __init.

Core Changes:
- Split DSC helpers from DP helpers.
- Clang build fixes for drm/mm test.
- Remove simple pipeline support for gem-vram,
  no longer any users left after converting bochs.
- Add erno to drm_sched_start to distinguish between GPU and queue
  reset.
- Add drm_framebuffer testcases.
- Fix uninitialized spinlock acquisition with CONFIG_DRM_PANIC=n.
- Use read_trylock instead of read_lock in dma_fence_begin_signalling to
  quiesce lockdep.

Driver Changes:
- Assorted small fixes and updates for tegra, host1x, imagination,
  nouveau, panfrost, panthor, panel/ili9341, mali, exynos,
  panel/samsung-s6e3fa7, ast, bridge/ti-sn65dsi86, panel/himax-hx83112a,
  bridge/tc358767, bridge/imx8mp-hdmi-tx, panel/khadas-ts050,
  panel/nt36523, panel/sony-acx565akm, kmb, accel/qaic, omap, v3d.
- Add bridge/TI TDP158.
- Assorted documentation updates.
- Convert bochs from simple drm to gem shmem, and check modes
  against available memory.
- Many VC4 fixes, most related to scaling and YUV support.
- Convert some drivers to use SYSTEM_SLEEP_PM_OPS and RUNTIME_PM_OPS.
- Rockchip 4k@60 support.

+it as needed. Usually a hang is detected when a job gets stuck executing.
+
+Propagation of errors to userspace has proven to be tricky since it goes in
+the opposite direction of the usual flow of commands. Because of this vendor
+independent error handling was added to the &dma_fence object, this way drivers
+can add an error code to their fences before signaling them. See function
+dma_fence_set_error() on how to do this and for examples of error codes to use.
+
+The DRM scheduler also allows setting error codes on all pending fences when
+hardware submissions are restarted after an reset. Error codes are also
+forwarded from the hardware fence to the scheduler fence to bubble up errors
+to the higher levels of the stack and eventually userspace.
+
+Fence errors can be queried by userspace through the generic SYNC_IOC_FILE_INFO
+IOCTL as well as through driver specific interfaces.
+
+Additional to setting fence errors drivers should also keep track of resets per
+context, the DRM scheduler provides the drm_sched_entity_error() function as
+helper for this use case. After a reset, KMD should reject new command
+submissions for affected contexts.

+Querying errors from drm_syncobj
+================================
+
+The drm_syncobj container can be used by driver independent code to signal
+complection of submission.
+
+One minor feature still missing is a generic DRM IOCTL to query the error
+status of binary and timeline drm_syncobj.
+
+This should probably be improved by implementing the necessary kernel interface
+and adding support for that in the userspace stack.
