+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", "bridge", and "core0"
+ register areas are always required. The "gca" register area
+ is required if the GCA cache controller is present.
+- interrupts: The interrupt numbers. The first interrupt is for the hub,
+ while the following inerrupts are for the cores.
+ See bindings/interrupt-controller/interrupts.txt
+
+Optional properties:
+- clocks: The core clock the unit runs on
