From 169f0a14f21a95194c5de355ce9a95d36aa97bef Mon Sep 17 00:00:00 2001

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.
