2 ------------------------------
3
4 This comphy controller can be found on Marvell Armada 38x. It provides a
5 number of shared PHYs used by various interfaces (network, sata, usb,
6 PCIe...).
7
8 Required properties:
9
10 - compatible: should be "marvell,armada-380-comphy"
11 - reg: should contain the comphy register location and length.
12 - #address-cells: should be 1.
13 - #size-cells: should be 0.
14
15 Optional properties:
16
17 - reg-names: must be "comphy" as the first name, and "conf".
18 - reg: must contain the comphy register location and length as the first
19 pair, followed by an optional configuration register address and
20 length pair.
21
22 A sub-node is required for each comphy lane provided by the comphy.
23
24 Required properties (child nodes):
25
26 - reg: comphy lane number.
27 - #phy-cells : from the generic phy bindings, must be 1. Defines the
28 input port to use for a given comphy lane.

30 Example:
31
32 comphy: phy@18300 {
33 compatible = "marvell,armada-380-comphy";
34 reg-names = "comphy", "conf";
35 reg = <0x18300 0x100>, <0x18460 4>;
36 #address-cells = <1>;
37 #size-cells = <0>;
38
39 cpm_comphy0: phy@0 {
40 reg = <0>;
41 #phy-cells = <1>;
42 };
43
44 cpm_comphy1: phy@1 {
45 reg = <1>;
46 #phy-cells = <1>;
47 };
48 };
