Subject: [PATCH 0/3] drm/simpledrm: Apple M1 / DT platform support fixes
Date: Wed, 17 Nov 2021 23:58:26 +0900	[thread overview]
Message-ID: <20211117145829.204360-1-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).

Hector Martin (3):
  drm/simpledrm: Bind to OF framebuffers in /chosen
  drm/format-helper: Add drm_fb_xrgb8888_to_xrgb2101010_dstclip()
  drm/simpledrm: Enable XRGB2101010 format
