  2. Required properties:
  3. - compatible: Must contain one of the following:
  4. - "renesas,usbhs-r8a7790"
  5. - "renesas,usbhs-r8a7791"
  6. - "renesas,usbhs-r8a7794"
  7. - reg: Base address and length of the register for the USBHS

  10. Optional properties:
  11. - renesas,buswait: Integer to use BUSWAIT register
  12. - renesas,enable-gpio: A gpio specifier to check GPIO determining if USB
  13. function should be enabled
