+mvebu armada 38x comphy driver
+------------------------------
+
+This comphy controller can be found on Marvell Armada 38x. It provides a
+number of shared PHYs used by various interfaces (network, sata, usb,
+PCIe...).
+
+Required properties:
+
+- compatible: should be "marvell,armada-380-comphy"
+- reg: should contain the comphy register location and length.
+- #address-cells: should be 1.
+- #size-cells: should be 0.
+
+A sub-node is required for each comphy lane provided by the comphy.
+
+Required properties (child nodes):
+
+- reg: comphy lane number.
+- #phy-cells : from the generic phy bindings, must be 1. Defines the
+               input port to use for a given comphy lane.
+
+Example:
+
+	comphy: phy@18300 {
+		compatible = "marvell,armada-380-comphy";
+		reg = <0x18300 0x100>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		cpm_comphy0: phy@0 {
+			reg = <0>;
+			#phy-cells = <1>;
+		};
+
+		cpm_comphy1: phy@1 {
+			reg = <1>;
+			#phy-cells = <1>;
+		};
+	};
