| 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. |
