Subject: [PATCH 0/2] of: Register platform device for each framebuffer
Date: Wed, 13 Apr 2022 11:24:52 +0200 [thread overview]
Message-ID: <20220413092454.1073-1-tzimmermann@suse.de> (raw)
Move the detection of OF framebuffers from fbdev into of platform code
and register a Linux platform device for each framebuffer. Allows for
DRM-based OF drivers and real hot-unplugging of the framebuffer.
This patchset has been tested with qemu's ppc64le emulation, which
provides a framebuffer via OF display node. If someone has an older
32-bit system with BootX available, please test.
