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
