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