The Marvell Armada 7K/8K SoCs contains an hardware block called COMPHY
that provides a number of shared PHYs used by various interfaces in the
SoC: network, SATA, PCIe, etc. This Device Tree binding allows to
describe this COMPHY hardware block.

+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>;
+               };
+       };
