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) Thomas Zimmermann (2): of: Create platform devices for OF framebuffers fbdev: Warn in hot-unplug workaround for framebuffers without device drivers/of/platform.c | 88 +++++++++++++++++++++------- drivers/video/fbdev/core/fbmem.c | 10 ++-- drivers/video/fbdev/offb.c | 98 +++++++++++++++++++++----------- 3 files changed, 136 insertions(+), 60 deletions(-) base-commit: d97978df553d768e457cb68c637b2b0a6188b87c prerequisite-patch-id: c2b2f08f0eccc9f5df0c0da49fa1d36267deb11d prerequisite-patch-id: c67e5d886a47b7d0266d81100837557fda34cb24 prerequisite-patch-id: 6e1032c6302461624f33194c8b8f37103a3fa6ef prerequisite-patch-id: 3f204510fcbf9530d6540bd8e6128cce598988b6 prerequisite-patch-id: ab7611d28d07723ab1dd392dcf9a6345de3b1040 -- 2.35.1
