Merge tag 'drm-misc-next-2023-11-17' of git://anongit.freedesktop.org/drm/drm-misc into drm-next

drm-misc-next for 6.8:

UAPI Changes:
  - drm: Introduce CLOSE_FB ioctl
  - drm/dp-mst: Documentation for the PATH property
  - fdinfo: Do not align to a MB if the size is larger than 1MiB
  - virtio-gpu: add explicit virtgpu context debug name

Cross-subsystem Changes:
  - dma-buf: Add dma_fence_timestamp helper

Core Changes:
  - client: Do not acquire module reference
  - edid: split out drm_eld, add SAD helpers
  - format-helper: Cache format conversion buffers
  - sched: Move from a kthread to a workqueue, rename some internal
    functions to make it clearer, implement dynamic job-flow control
  - gpuvm: Provide more features to handle GEM objects
  - tests: Remove slow kunit tests

Driver Changes:
  - ivpu: Update FW API, new debugfs file, a new NOP job submission test
    mode, improve suspend/resume, PM improvements, MMU PT optimizations,
    firmware profiling frequency support, support for uncached buffers,
    switch to gem shmem helpers, replace kthread with threaded
    interrupts
  - panfrost: PM improvements
  - qaic: Allow to run with a single MSI, support host/device time
    synchronization, misc improvements
  - simplefb: Support memory-regions, support power-domains
  - ssd130x: Unitialized variable fixes
  - omapdrm: dma-fence lockdep annotation fix
  - tidss: dma-fence lockdep annotation fix
  - v3d: Support BCM2712 (RaspberryPi5), Support fdinfo and gputop
  - panel:
    - edp: Support AUO B116XTN02, BOE NT116WHM-N21,836X2, NV116WHM-N49
      V8.0, plus a whole bunch of panels used on Mediatek chromebooks.

Note that the one missing s-o-b for 0da611a87021 ("dma-buf: add
dma_fence_timestamp helper") has been supplied here, and rebasing the
entire tree with upsetting committers didn't seem worth the trouble:

+ * DRM_IOCTL_MODE_CLOSEFB - Close a framebuffer.
+ *
+ * This closes a framebuffer previously added via ADDFB/ADDFB2. The IOCTL
+ * argument is a framebuffer object ID.
+ *
+ * This IOCTL is similar to &DRM_IOCTL_MODE_RMFB, except it doesn't disable
+ * planes and CRTCs. As long as the framebuffer is used by a plane, it's kept
+ * alive. When the plane no longer uses the framebuffer (because the
+ * framebuffer is replaced with another one, or the plane is disabled), the
+ * framebuffer is cleaned up.
+ *
+ * This is useful to implement flicker-free transitions between two processes.
+ *
+ * Depending on the threat model, user-space may want to ensure that the
+ * framebuffer doesn't expose any sensitive user information: closed
+ * framebuffers attached to a plane can be read back by the next DRM master.
