+mvebu comphy driver
+-------------------
+
+A comphy controller can be found on Marvell Armada 7k/8k on the CP110. It
+provides a number of shared PHYs used by various interfaces (network, sata,
+usb, PCIe...).
+
+Required properties:
+
+- compatible: should be "marvell,comphy-cp110"
+- reg: should contain the comphy register location and length.
+- marvell,system-controller: should contain a phandle to the
+ system controller node.
+- #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:
+
+ cpm_comphy: phy@120000 {
+ compatible = "marvell,comphy-cp110";
+ reg = <0x120000 0x6000>;
+ marvell,system-controller = <&cpm_syscon0>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ cpm_comphy0: phy@0 {
+ reg = <0>;
+ #phy-cells = <1>;
+ };
+
+ cpm_comphy1: phy@1 {
+ reg = <1>;
+ #phy-cells = <1>;
+ };
+ };
