Hisilicon MDIO bus controller
Properties:
- compatible: can be one of:
"hisilicon,hns-mdio"
"hisilicon,mdio"
"hisilicon,hns-mdio" is recommended to be used for hip05 and later SOCs,
while "hisilicon,mdio" is optional for backwards compatibility only on
hip04 Soc.
- reg: The base address of the MDIO bus controller register bank.
- #address-cells: Must be <1>.
- #size-cells: Must be <0>. MDIO addresses have no size component.
Typically an MDIO bus might have several children.
Example:
mdio@803c0000 {
#address-cells = <1>;
#size-cells = <0>;
compatible = "hisilicon,hns-mdio","hisilicon,mdio";
reg = <0x0 0x803c0000 0x0 0x10000>;
ethernet-phy@0 {
...
reg = <0>;
};
};
