|
||
|
|
||
|
MDIO node is defined to describe on-chip MDIO controller.
|
||
|
|
||
|
Required properties:
|
||
|
- compatible: Must be "apm,xgene-mdio-rgmii" or "apm,xgene-mdio-xfi"
|
||
|
- #address-cells: Must be <1>.
|
||
|
- #size-cells: Must be <0>.
|
||
|
- reg: Address and length of the register set
|
||
|
- clocks: Reference to the clock entry
|
||
|
|
||
|
For the phys on the mdio bus, there must be a node with the following fields:
|
||
|
- compatible: PHY identifier. Please refer ./phy.txt for the format.
|
||
|
- reg: The ID number for the phy.
|
||
|
|
||
|
Example:
|
||
|
|
||
|
mdio: mdio@17020000 {
|
||
|
compatible = "apm,xgene-mdio-rgmii";
|
||
|
#address-cells = <1>;
|
||
|
#size-cells = <0>;
|
||
|
reg = <0x0 0x17020000 0x0 0xd100>;
|
||
|
clocks = <&menetclk 0>;
|
||
|
};
|
||
|
|
||
|
/* Board-specific peripheral configurations */

|
&mdio {
|
||
|
menetphy: phy@3 {
|
||
|
reg = <0x3>;
|
||
|
};
|
||
|
sgenet0phy: phy@4 {
|
||
|
reg = <0x4>;
