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.
