Merge tag 'drm-misc-next-2023-01-12' of git://anongit.freedesktop.org/drm/drm-misc into drm-next

drm-misc-next for v6.3:

UAPI Changes:

 * fourcc: Document Open Source user waiver

Cross-subsystem Changes:

 * firmware: fix color-format selection for system framebuffers

Core Changes:

 * format-helper: Add conversion from XRGB8888 to various sysfb formats;
   Make XRGB8888 the only driver-emulated legacy format

 * fb-helper: Avoid blank consoles from selecting an incorrect color format

 * probe-helper: Enable/disable HPD on connectors plus driver updates

 * Use drm_dbg_ helpers in several places

 * docs: Document defaults for CRTC backgrounds; Document use of drm_minor

Driver Changes:

 * arm/hdlcd: Use new debugfs helpers

 * gud: Use new debugfs helpers

 * panel: Support Visionox VTDR6130 AMOLED DSI; Support Himax HX8394; Convert
   many drivers to common generic DSI write-sequence helper

 * v3d: Do not opencode drm_gem_object_lookup()

 * vc4: Various HVS an CRTC fixes

 * vkms: Fix SEGFAULT from incorrect GEM-buffer mapping

 * Convert various drivers to i2c probe_new()
