Subject: [PATCH] drm/vc4: Add FKMS as an acceptable node for dma
|
|
|
|
|
ranges.
|
|
|
|
|
|
|
|
|
|
Under FKMS, the firmware (via FKMS) also requires the VideoCore cache
|
|
|
|
|
aliases for image planes, as defined by the dma-ranges under /soc.
|
|
|
|
|
|
|
|
|
|
Add rpi-firmware-kms to the list of acceptable nodes to look for
|
|
|
|
|
to copy dma config from.
