Subject: [PATCH v2 0/2] of: Register platform device for each framebuffer
Date: Tue, 19 Apr 2022 12:04:03 +0200 [thread overview]
Message-ID: <20220419100405.12600-1-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.
v2:
* integrate PPC code into generic platform setup (Rob)
* keep !device workaround with a warning (Javier, Daniel)
