+Renesas Electronics USBHS driver
+
+Required properties:
+ - compatible: Must contain one or more of the following:
+
+ - "renesas,usbhs-r8a7743" for r8a7743 (RZ/G1M) compatible device
+ - "renesas,usbhs-r8a7745" for r8a7745 (RZ/G1E) compatible device
+ - "renesas,usbhs-r8a7790" for r8a7790 (R-Car H2) compatible device
+ - "renesas,usbhs-r8a7791" for r8a7791 (R-Car M2-W) compatible device
+ - "renesas,usbhs-r8a7792" for r8a7792 (R-Car V2H) compatible device
+ - "renesas,usbhs-r8a7793" for r8a7793 (R-Car M2-N) compatible device
+ - "renesas,usbhs-r8a7794" for r8a7794 (R-Car E2) compatible device
+ - "renesas,usbhs-r8a7795" for r8a7795 (R-Car H3) compatible device
+ - "renesas,usbhs-r8a7796" for r8a7796 (R-Car M3-W) compatible device
+ - "renesas,usbhs-r8a77965" for r8a77965 (R-Car M3-N) compatible device
+ - "renesas,usbhs-r8a77995" for r8a77995 (R-Car D3) compatible device
+ - "renesas,usbhs-r7s72100" for r7s72100 (RZ/A1) compatible device
+ - "renesas,rcar-gen2-usbhs" for R-Car Gen2 or RZ/G1 compatible devices
+ - "renesas,rcar-gen3-usbhs" for R-Car Gen3 compatible device
+ - "renesas,rza1-usbhs" for RZ/A1 compatible device
+
+ When compatible with the generic version, nodes must list the
+ SoC-specific version corresponding to the platform first followed
+ by the generic version.
+
+ - 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"
+ - dmas: Must contain a list of references to DMA specifiers.
+ - dma-names : named "ch%d", where %d is the channel number ranging from zero
+ to the number of channels (DnFIFOs) minus one.
+
+Example:
+ usbhs: usb@e6590000 {
+ compatible = "renesas,usbhs-r8a7790", "renesas,rcar-gen2-usbhs";
+ reg = <0 0xe6590000 0 0x100>;
+ interrupts = <0 107 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&mstp7_clks R8A7790_CLK_HSUSB>;
+ };
