+Renesas Electronics USB3.0 Peripheral driver
+
+Required properties:
+  - compatible: Must contain one of the following:
+	- "renesas,r8a7795-usb3-peri"
+	- "renesas,r8a7796-usb3-peri"
+	- "renesas,r8a77965-usb3-peri"
+	- "renesas,rcar-gen3-usb3-peri" for a generic R-Car Gen3 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 USB3.0 Peripheral
+  - interrupts: Interrupt specifier for the USB3.0 Peripheral
+  - clocks: clock phandle and specifier pair
+
+Optional properties:
+  - phys: phandle + phy specifier pair
+  - phy-names: must be "usb"
+
+Example of R-Car H3 ES1.x:
+	usb3_peri0: usb@ee020000 {
+		compatible = "renesas,r8a7795-usb3-peri",
+			     "renesas,rcar-gen3-usb3-peri";
+		reg = <0 0xee020000 0 0x400>;
+		interrupts = <GIC_SPI 104 IRQ_TYPE_LEVEL_HIGH>;
+		clocks = <&cpg CPG_MOD 328>;
+	};
+
+	usb3_peri1: usb@ee060000 {
+		compatible = "renesas,r8a7795-usb3-peri",
+			     "renesas,rcar-gen3-usb3-peri";
+		reg = <0 0xee060000 0 0x400>;
+		interrupts = <GIC_SPI 100 IRQ_TYPE_LEVEL_HIGH>;
+		clocks = <&cpg CPG_MOD 327>;
+	};
