1 APM X-Gene SoC MDIO node
2
3 MDIO node is defined to describe on-chip MDIO controller.
4
5 Required properties:
6 - compatible: Must be "apm,xgene-mdio-rgmii" or "apm,xgene-mdio-xfi"
7 - #address-cells: Must be <1>.
8 - #size-cells: Must be <0>.
9 - reg: Address and length of the register set
10 - clocks: Reference to the clock entry
11
12 For the phys on the mdio bus, there must be a node with the following fields:
13 - compatible: PHY identifier. Please refer ./phy.txt for the format.
14 - reg: The ID number for the phy.
15
16 Example:
17
18 mdio: mdio@17020000 {
19 compatible = "apm,xgene-mdio-rgmii";
20 #address-cells = <1>;
21 #size-cells = <0>;
22 reg = <0x0 0x17020000 0x0 0xd100>;
23 clocks = <&menetclk 0>;
24 };
25
26 /* Board-specific peripheral configurations */
27 &mdio {
28 menetphy: phy@3 {
29 reg = <0x3>;
30 };
31 sgenet0phy: phy@4 {
32 reg = <0x4>;
33 };
34 sgenet1phy: phy@5 {
35 reg = <0x5>;
36 };
37 };
