   3 Required properties:
   4   - compatible: Must contain one of the following:
   5         - "renesas,usbhs-r8a7790"
   6         - "renesas,usbhs-r8a7791"
   7         - "renesas,usbhs-r8a7794"
   8   - reg: Base address and length of the register for the USBHS
   9   - interrupts: Interrupt specifier for the USBHS
  10   - clocks: A list of phandle + clock specifier pairs
  11
  12 Optional properties:
  13   - renesas,buswait: Integer to use BUSWAIT register
  14   - renesas,enable-gpio: A gpio specifier to check GPIO determining if USB
  15                          function should be enabled
  16   - phys: phandle + phy specifier pair
  17   - phy-names: must be "usb"
  18   - dmas: Must contain a list of references to DMA specifiers.
  19   - dma-names : named "ch%d", where %d is the channel number ranging from zero
  20                 to the number of channels (DnFIFOs) minus one.

  22 Example:
  23         usbhs: usb@e6590000 {
  24                 compatible = "renesas,usbhs-r8a7790";
  25                 reg = <0 0xe6590000 0 0x100>;
  26                 interrupts = <0 107 IRQ_TYPE_LEVEL_HIGH>;
