   4 Subject: [PATCH] drm/vc4: Add FKMS as an acceptable node for dma
   5  ranges.
   6
   7 Under FKMS, the firmware (via FKMS) also requires the VideoCore cache
   8 aliases for image planes, as defined by the dma-ranges under /soc.
   9
  10 Add rpi-firmware-kms to the list of acceptable nodes to look for
  11 to copy dma config from.
