Merge tag 'drm-misc-next-2023-07-13' of git://anongit.freedesktop.org/drm/drm-misc into drm-next

drm-misc-next for v6.6:

UAPI Changes:

 * fbdev:
   * Make fbdev userspace interfaces optional; only leaves the
     framebuffer console active

 * prime:
   * Support dma-buf self-import for all drivers automatically: improves
     support for many userspace compositors

Cross-subsystem Changes:

 * backlight:
   * Fix interaction with fbdev in several drivers

 * base: Convert struct platform.remove to return void; part of a larger,
   tree-wide effort

 * dma-buf: Acquire reservation lock for mmap() in exporters; part
   of an on-going effort to simplify locking around dma-bufs

 * fbdev:
   * Use Linux device instead of fbdev device in many places
   * Use deferred-I/O helper macros in various drivers

 * i2c: Convert struct i2c from .probe_new to .probe; part of a larger,
   tree-wide effort

 * video:
   * Avoid including <linux/screen_info.h>

Core Changes:

 * atomic:
   * Improve logging

 * prime:
   * Remove struct drm_driver.gem_prime_mmap plus driver updates: all
     drivers now implement this callback with drm_gem_prime_mmap()

 * gem:
   * Support execution contexts: provides locking over multiple GEM
     objects

 * ttm:
   * Support init_on_free
   * Swapout fixes

Driver Changes:

 * accel:
   * ivpu: MMU updates; Support debugfs

 * ast:
   * Improve device-model detection
   * Cleanups

 * bridge:
   * dw-hdmi: Improve support for YUV420 bus format
   * dw-mipi-dsi: Fix enable/disable of DSI controller
   * lt9611uxc: Use MODULE_FIRMWARE()
   * ps8640: Remove broken EDID code
   * samsung-dsim: Fix command transfer
   * tc358764: Handle HS/VS polarity; Use BIT() macro; Various cleanups
   * Cleanups

 * ingenic:
   * Kconfig REGMAP fixes

 * loongson:
   * Support display controller

 * mgag200:
   * Minor fixes

 * mxsfb:
   * Support disabling overlay planes

 * nouveau:
   * Improve VRAM detection
   * Various fixes and cleanups

 * panel:
   * panel-edp: Support AUO B116XAB01.4
   * Support Visionox R66451 plus DT bindings
   * Cleanups

 * ssd130x:
   * Support per-controller default resolution plus DT bindings
   * Reduce memory-allocation overhead
   * Cleanups

 * tidss:
   * Support TI AM625 plus DT bindings
   * Implement new connector model plus driver updates

 * vkms
   * Improve write-back support
   * Documentation fixes
