Merge tag 'drm-misc-next-2023-12-07' of git://anongit.freedesktop.org/drm/drm-misc into drm-next 



drm-misc-next for 6.8:

UAPI Changes:
  - Remove Userspace Mode-Setting ioctls
  - v3d: New uapi to handle jobs involving the CPU

Cross-subsystem Changes:

Core Changes:
  - atomic: Add support for FB-less planes which got reverted a bit
    later for lack of IGT tests and userspace code, Dump private objects
    state in drm_state_dump.
  - dma-buf: Add fence deadline support
  - encoder: Create per-encoder debugfs directory, move the bridge chain
    file to that directory

Driver Changes:
  - Include drm_auth.h in driver that use it but don't include it, Drop
    drm_plane_helper.h from drivers that include it but don't use it
  - imagination: Plenty of small fixes
  - panfrost: Improve interrupt handling at poweroff
  - qaic: Convert to persistent DRM devices
  - tidss: Support for the AM62A7, a few probe improvements, some cleanups
  - v3d: Support for jobs involving the CPU

  - bridge:
    - Create transparent aux-bridge for DP/USB-C
    - lt8912b: Add suspend/resume support and power regulator support

  - panel:
    - himax-hx8394: Drop prepare, unprepare and shutdown logic, Support
      panel rotation
    - New panels: BOE BP101WX1-100, Powkiddy X55, Ampire AM8001280G,

uAPI

====



QAIC creates an accel device per phsyical PCIe device. This accel device exists

for as long as the PCIe device is known to Linux.



The PCIe device may not be in the state to accept requests from userspace at

all times. QAIC will trigger KOBJ_ONLINE/OFFLINE uevents to advertise when the

device can accept requests (ONLINE) and when the device is no longer accepting

requests (OFFLINE) because of a reset or other state transition.



QAIC defines a number of driver specific IOCTLs as part of the userspace API.

This section describes those APIs.



DRM_IOCTL_QAIC_MANAGE

  This IOCTL allows userspace to send a NNC request to the QSM. The call will
