| 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 | }; |
