From eccaa8588fca9c9ec950664f1d5894bd826b57b0 Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Mon, 23 Oct 2023 14:10:15 +0100 Subject: [PATCH] dt: Add drm_fbN_vc4 overrides for Pi0-4 Follows up '61b138adaead ("dt: Add overrides for drm framebuffer allocations on Pi5")' with an equivalent for Pi0-4. These will have no effect on most normal systems, but drm_fb0_vc4 will stop SPI displays jumping in and claiming /dev/fb0.
