drm-misc-next for v5.15:

UAPI Changes:
- Add modifiers for arm fixed rate compression.

Cross-subsystem Changes:
- Assorted dt binding fixes.
- Convert ssd1307fb to json-schema.
- Update a lot of irc channels to point to OFTC, as everyone moved there.
- Fix the same divide by zero for asilantfb, kyro, rivafb.

Core Changes:
- Document requirements for new atomic properties.
- Add drm_gem_fb_(begin/end)_cpu_access helpers, and use them in some drivers.
- Document drm_property_enum.value for bitfields.
- Add explicit _NO_ for MIPI_DSI flags that disable features.
- Assorted documentation fixes.
- Update fb_damage handling, and move drm_plane_enable_fb_damage_clips to core.
- Add logging and docs to RMFB ioctl.
- Assorted small fixes to dp_mst, master handling.
- Clarify drm lease usage.

Driver Changes:
- Assorted small fixes to panfrost, hibmc, bridge/nwl-dsi, rockchip, vc4.
- More drm -> linux irq conversions.
- Add support for some Logic Technologies and Multi-Inno panels.
- Expose phy-functionality for drm/rockchip, to allow controlling from the media subsystem.
- Add support for 2 AUO panels.
- Add damage handling to ssd1307fb.
- Improve FIFO handling on mxsfb.
- Assorted small fixes to vmwgfx, and bump version to 2.19 for the new ioctls.
- Improve sony acx424akp backlight handling.
