drm-misc-next for v5.3:

UAPI Changes:

Cross-subsystem Changes:
- Add code to signal all dma-fences when freed with pending signals.
- Annotate reservation object access in CONFIG_DEBUG_MUTEXES

Core Changes:
- Assorted documentation fixes.
- Use irqsave/restore spinlock to add crc entry.
- Move code around to drm_client, for internal modeset clients.
- Make drm_crtc.h and drm_debugfs.h self-contained.
- Remove drm_fb_helper_connector.
- Add bootsplash to todo.
- Fix lock ordering in pan_display_legacy.
- Support pinning buffers to current location in gem-vram.
- Remove the now unused locking functions from gem-vram.
- Remove the now unused kmap-object argument from vram helpers.
- Stop checking return value of debugfs_create.
- Add atomic encoder enable/disable helpers.
- pass drm_atomic_state to atomic connector check.
- Add atomic support for bridge enable/disable.
- Add self refresh helpers to core.

Driver Changes:
- Add extra delay to make MTP SDM845 work.
- Small fixes to virtio, vkms, sii902x, sii9234, ast, mcde, analogix, rockchip.
- Add zpos and ?BGR8888 support to meson.
- More removals of drm_os_linux and drmP headers for amd, radeon, sti, r128, r128, savage, sis.
- Allow synopsis to unwedge the i2c hdmi bus.
- Add orientation quirks for GPD panels.
- Edid cleanups and fixing handling for edid < 1.2.
- Add runtime pm to stm.
- Handle s/r in dw-hdmi.
- Add hooks for power on/off to dsi for stm.
- Remove virtio dirty tracking code, done in drm core.
- Rework BO handling in ast and mgag200.

Tiny conflict in drivers/gpu/drm/amd/display/dc/clk_mgr/clk_mgr.c,
needed #include <linux/slab.h> to make it compile.
