   3 Required properties:
   4   - compatible: Must contain one of the following:
   5         - "renesas,r8a774a1-usb3-peri"
   6         - "renesas,r8a7795-usb3-peri"
   7         - "renesas,r8a7796-usb3-peri"
   8         - "renesas,r8a77965-usb3-peri"
   9         - "renesas,rcar-gen3-usb3-peri" for a generic R-Car Gen3 or RZ/G2
  10           compatible device
  11
  12     When compatible with the generic version, nodes must list the
  13     SoC-specific version corresponding to the platform first
  14     followed by the generic version.
  15
  16   - reg: Base address and length of the register for the USB3.0 Peripheral
  17   - interrupts: Interrupt specifier for the USB3.0 Peripheral
  18   - clocks: clock phandle and specifier pair
  19
  20 Optional properties:
  21   - phys: phandle + phy specifier pair
  22   - phy-names: must be "usb"
