1mvebu comphy driver
2-------------------
3
4A comphy controller can be found on Marvell Armada 7k/8k on the CP110. It
5provides a number of shared PHYs used by various interfaces (network, sata,
6usb, PCIe...).
7
8Required properties:
9
10- compatible: should be "marvell,comphy-cp110"
11- reg: should contain the comphy register location and length.
12- marvell,system-controller: should contain a phandle to the
13 system controller node.
14- #address-cells: should be 1.
15- #size-cells: should be 0.
16
17A sub-node is required for each comphy lane provided by the comphy.
18
19Required properties (child nodes):
20
21- reg: comphy lane number.
22- #phy-cells : from the generic phy bindings, must be 1. Defines the
23 input port to use for a given comphy lane.
24
25Example:
26
27 cpm_comphy: phy@120000 {
28 compatible = "marvell,comphy-cp110";
29 reg = <0x120000 0x6000>;
30 marvell,system-controller = <&cpm_syscon0>;
31 #address-cells = <1>;
32 #size-cells = <0>;
33
34 cpm_comphy0: phy@0 {
35 reg = <0>;
36 #phy-cells = <1>;
37 };
38
39 cpm_comphy1: phy@1 {
40 reg = <1>;
41 #phy-cells = <1>;
42 };
43 };
