Subject: [PATCH] dt: Add overrides for drm framebuffer allocations on Pi5
|
|
|
|
Adds dtparam overrides to the base Pi5 DT such that vc4,
|
|
DSI0, DSI1, or DPI can be requested to be /dev/fb[012].
|
|
No override is specified by default, so the order will be
|
|
based on probe order (aka semi-random). Any device that
|
|
doesn't have an override specified will be placed above
|
|
all specified overrides. Having an fb1 or fb2 override but
|
|
no fb0 one will result in no console via fbcon.
