| 2 | |
| 3 | Only the Broadcom V3D 3.x and newer GPUs are covered by this binding. |
| 4 | For V3D 2.x, see brcm,bcm-vc4.txt. |
| 5 | |
| 6 | Required properties: |
| 7 | - compatible: Should be "brcm,7268-v3d" or "brcm,7278-v3d" |
| 8 | - reg: Physical base addresses and lengths of the register areas |
| 9 | - reg-names: Names for the register areas. The "hub" and "core0" |
| 10 | register areas are always required. The "gca" register area |
| 11 | is required if the GCA cache controller is present. The |
| 12 | "bridge" register area is required if an external reset |
| 13 | controller is not present. |
| 14 | - interrupts: The interrupt numbers. The first interrupt is for the hub, |
| 15 | while the following interrupts are separate interrupt lines |
| 16 | for the cores (if they don't share the hub's interrupt). |
| 17 | See bindings/interrupt-controller/interrupts.txt |
| 18 | |
| 19 | Optional properties: |
| 20 | - clocks: The core clock the unit runs on |
| 21 | - resets: The reset line for v3d, if not using a mapping of the bridge |
| 22 | See bindings/reset/reset.txt |
