     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
