+Renesas Electronics USBHS driver
+
+Required properties:
+ - compatible: Must contain one of the following:
+ - "renesas,usbhs-r8a7790"
+ - "renesas,usbhs-r8a7791"
+ - 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
+
+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"
+
+Example:
+ usbhs: usb@e6590000 {
+ compatible = "renesas,usbhs-r8a7790";
+ reg = <0 0xe6590000 0 0x100>;
+ interrupts = <0 107 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&mstp7_clks R8A7790_CLK_HSUSB>;
+ };
