+* Marvell Berlin USB PHY
+
+Required properties:
+- compatible: should be "marvell,berlin-usbphy"
+- reg: base address and length of the registers
+- #phys-cells: should be 0
+- reset: reference to the reset controller
+- power-gpio: reference the GPIO pin to power the PHY
+
+Example:
+
+	usbphy@f774000 {
+		compatible = "marvell,berlin-usbphy";
+		reg = <0xf774000 0x128>;
+		#phy-cells = <0>;
+		resets = <&chip 14>;
+		power-gpio = <&portb 8 GPIO_ACTIVE_HIGH>;
+	};
