	- "renesas,usbhs-r8a77995" for r8a77995 (R-Car D3) compatible device

	- "renesas,usbhs-r7s72100" for r7s72100 (RZ/A1) compatible device

	- "renesas,usbhs-r7s9210" for r7s9210 (RZ/A2) compatible device

	- "renesas,rcar-gen2-usbhs" for R-Car Gen2 or RZ/G1 compatible devices

	- "renesas,rcar-gen3-usbhs" for R-Car Gen3 or RZ/G2 compatible devices

	- "renesas,rza1-usbhs" for RZ/A1 compatible device

	- "renesas,rza2-usbhs" for RZ/A2 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 USBHS

  - interrupts: Interrupt specifier for the USBHS

  - clocks: A list of phandle + clock specifier pairs.

	    - In case of "renesas,rcar-gen3-usbhs", two clocks are required.

	      First clock should be peripheral and second one should be host.

	    - In case of except above, one clock is required. First clock

	      should be peripheral.

Optional properties:

  - renesas,buswait: Integer to use BUSWAIT register

  - renesas,enable-gpio: A gpio specifier to check GPIO determining if USB

			 function should be enabled

  - phys: phandle + phy specifier pair

  - phy-names: must be "usb"

  - dmas: Must contain a list of references to DMA specifiers.

  - dma-names : named "ch%d", where %d is the channel number ranging from zero

                to the number of channels (DnFIFOs) minus one.

Example:

	usbhs: usb@e6590000 {

		compatible = "renesas,usbhs-r8a7790", "renesas,rcar-gen2-usbhs";

		reg = <0 0xe6590000 0 0x100>;

		interrupts = <0 107 IRQ_TYPE_LEVEL_HIGH>;

		clocks = <&mstp7_clks R8A7790_CLK_HSUSB>;
