   3 Required properties:
   4   - compatible: Must contain one or more of the following:
   5
   6         - "renesas,usbhs-r8a7790" for r8a7790 (R-Car H2) compatible device
   7         - "renesas,usbhs-r8a7791" for r8a7791 (R-Car M2-W) compatible device
   8         - "renesas,usbhs-r8a7792" for r8a7792 (R-Car V2H) compatible device
   9         - "renesas,usbhs-r8a7793" for r8a7793 (R-Car M2-N) compatible device
  10         - "renesas,usbhs-r8a7794" for r8a7794 (R-Car E2) compatible device
  11         - "renesas,usbhs-r8a7795" for r8a7795 (R-Car H3) compatible device
  12         - "renesas,usbhs-r8a7796" for r8a7796 (R-Car M3-W) compatible device
  13         - "renesas,rcar-gen2-usbhs" for R-Car Gen2 compatible device
  14         - "renesas,rcar-gen3-usbhs" for R-Car Gen3 compatible device
  15
  16         When compatible with the generic version, nodes must list the
  17         SoC-specific version corresponding to the platform first followed
  18         by the generic version.
  19
  20   - reg: Base address and length of the register for the USBHS
  21   - interrupts: Interrupt specifier for the USBHS
  22   - clocks: A list of phandle + clock specifier pairs
  23
  24 Optional properties:
  25   - renesas,buswait: Integer to use BUSWAIT register
  26   - renesas,enable-gpio: A gpio specifier to check GPIO determining if USB
  27                          function should be enabled
  28   - phys: phandle + phy specifier pair
  29   - phy-names: must be "usb"
  30   - dmas: Must contain a list of references to DMA specifiers.
  31   - dma-names : named "ch%d", where %d is the channel number ranging from zero
  32                 to the number of channels (DnFIFOs) minus one.

  34 Example:
  35         usbhs: usb@e6590000 {
  36                 compatible = "renesas,usbhs-r8a7790", "renesas,rcar-gen2-usbhs";
  37                 reg = <0 0xe6590000 0 0x100>;
  38                 interrupts = <0 107 IRQ_TYPE_LEVEL_HIGH>;
  39                 clocks = <&mstp7_clks R8A7790_CLK_HSUSB>;
  40         };
