+- compatible: "marvell,armada-375-usb-cluster"
+- reg: Should contain usb cluster register location and length.
+- #phy-cells : from the generic phy bindings, must be 1
+
+Example:
+	usbcluster: usb-cluster at 18400 {
+		compatible = "marvell,armada-375-usb-cluster";
+		reg = <0x18400 0x4>;
+		#phy-cells = <1>
