| 2 | |
| 3 | Properties: |
| 4 | - compatible: can be one of: |
| 5 | "hisilicon,hns-mdio" |
| 6 | "hisilicon,mdio" |
| 7 | "hisilicon,hns-mdio" is recommended to be used for hip05 and later SOCs, |
| 8 | while "hisilicon,mdio" is optional for backwards compatibility only on |
| 9 | hip04 Soc. |
| 10 | - reg: The base address of the MDIO bus controller register bank. |
| 11 | - #address-cells: Must be <1>. |
| 12 | - #size-cells: Must be <0>. MDIO addresses have no size component. |
| 13 | |
| 14 | Typically an MDIO bus might have several children. |
| 15 | |
| 16 | Example: |
| 17 | mdio@803c0000 { |
| 18 | #address-cells = <1>; |
| 19 | #size-cells = <0>; |
| 20 | compatible = "hisilicon,hns-mdio","hisilicon,mdio"; |
| 21 | reg = <0x0 0x803c0000 0x0 0x10000>; |
| 22 | |
| 23 | ethernet-phy@0 { |
| 24 | ... |
| 25 | reg = <0>; |
| 26 | }; |
| 27 | }; |
