   3 Required properties:
   4   - compatible: Must contain one of the following:
   5         - "renesas,usbhs-r8a7790"
   6         - "renesas,usbhs-r8a7791"
   7   - reg: Base address and length of the register for the USBHS
   8   - interrupts: Interrupt specifier for the USBHS
   9   - clocks: A list of phandle + clock specifier pairs
  10
  11 Optional properties:
  12   - renesas,buswait: Integer to use BUSWAIT register
  13   - renesas,enable-gpio: A gpio specifier to check GPIO determining if USB
  14                          function should be enabled
  15   - phys: phandle + phy specifier pair
  16   - phy-names: must be "usb"
  17   - dmas: Must contain a list of references to DMA specifiers.
  18   - dma-names : Must contain a list of DMA names:
  19    - tx0 ... tx<n>
  20    - rx0 ... rx<n>
  21     - This <n> means DnFIFO in USBHS module.

  23 Example:
  24         usbhs: usb@e6590000 {
  25                 compatible = "renesas,usbhs-r8a7790";
  26                 reg = <0 0xe6590000 0 0x100>;
  27                 interrupts = <0 107 IRQ_TYPE_LEVEL_HIGH>;
  28                 clocks = <&mstp7_clks R8A7790_CLK_HSUSB>;
  29         };
