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>;
};
};
