-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
-
