Subject: [PATCH v3 0/3] drm/simpledrm: Apple M1 / DT platform support fixes
Date: Sun, 12 Dec 2021 15:24:04 +0900	[thread overview]
Message-ID: <20211212062407.138309-1-marcan@marcan.st> (raw)

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 v2:
- Made 10-bit conversion code fill the LSBs
- Added ARGB2101010 to supported formats list
- Simplified OF core code per review feedback
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 [AX]RGB2101010 formats
