Required properties:

  - compatible: Must contain one of the following:

	- "renesas,r8a7795-usb3-peri"

	- "renesas,r8a7796-usb3-peri"

	- "renesas,rcar-gen3-usb3-peri" for a generic R-Car Gen3 compatible

	  device



    When compatible with the generic version, nodes must list the

    SoC-specific version corresponding to the platform first

    followed by the generic version.



  - reg: Base address and length of the register for the USB3.0 Peripheral

  - interrupts: Interrupt specifier for the USB3.0 Peripheral

  - clocks: clock phandle and specifier pair

Example of R-Car H3 ES1.x:
