+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.
+
+Optional properties:
+
+- reg-names: must be "comphy" as the first name, and "conf".
+- reg: must contain the comphy register location and length as the first
+ pair, followed by an optional configuration register address and
+ length pair.
+
+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-names = "comphy", "conf";
+ reg = <0x18300 0x100>, <0x18460 4>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ cpm_comphy0: phy@0 {
+ reg = <0>;
+ #phy-cells = <1>;
+ };
+
+ cpm_comphy1: phy@1 {
+ reg = <1>;
+ #phy-cells = <1>;
+ };
+ };
