Hi DRM folks,
This short series makes simpledrm work on Apple M1 (including Pro/Max) platforms the way simplefb already does, by adding XRGB2101010 support and making it bind to framebuffers in /chosen the same way simplefb does.
This avoids breaking the bootloader-provided framebuffer console when simpledrm is selected to replace simplefb, as these FBs always seem to be 10-bit (at least when a real screen is attached).
Changes since v1: - Moved the OF platform device setup code from simplefb into common code, instead of duplicating it in simpledrm - Rebased on drm-tip
Hector Martin (3): of: Move simple-framebuffer device handling from simplefb to of drm/format-helper: Add drm_fb_xrgb8888_to_xrgb2101010_toio() drm/simpledrm: Add XRGB2101010 format
