* System Management Interface (SMI) / MDIO
Properties:
- compatible: One of:
"cavium,octeon-3860 -mdio": Compatibility with all cn3XXX, cn5XXX
and cn6XXX SOCs.
"cavium,thunder-8890 -mdio": Compatibility with all cn8XXX SOCs.
- 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@1180000001800 {
compatible = "cavium,octeon-3860 -mdio";
#address-cells = <1 >;
#size-cells = <0 >;
reg = <0 x11800 0 x00001800 0 x0 0 x40>;
ethernet-phy@0 {
...
reg = <0 >;
};
};
* System Management Interface (SMI) / MDIO Nexus
Several mdio buses may be gathered as children of a single PCI
device, this PCI device is the nexus of the buses.
Properties:
- compatible: "cavium,thunder-8890 -mdio-nexus";
- reg: The PCI device and function numbers of the nexus device.
- #address-cells: Must be <2 >.
- #size-cells: Must be <2 >.
- ranges: As needed for mapping of the MDIO bus device registers.
- assigned-addresses: As needed for mapping of the MDIO bus device registers.
Example:
mdio-nexus@1 ,3 {
compatible = "cavium,thunder-8890 -mdio-nexus";
#address-cells = <2 >;
#size-cells = <2 >;
reg = <0 x0b00 0 0 0 0 >; /* DEVFN = 0 x0b (1 :3 ) */
assigned-addresses = <0 x03000000 0 x87e0 0 x05000000 0 x0 0 x800000>;
ranges = <0 x87e0 0 x05000000 0 x03000000 0 x87e0 0 x05000000 0 x0 0 x800000>;
mdio0@87 e0,05003800 {
compatible = "cavium,thunder-8890 -mdio";
#address-cells = <1 >;
#size-cells = <0 >;
reg = <0 x87e0 0 x05003800 0 x0 0 x30>;
ethernet-phy@0 {
...
reg = <0 >;
};
};
mdio0@87 e0,05003880 {
compatible = "cavium,thunder-8890 -mdio";
#address-cells = <1 >;
#size-cells = <0 >;
reg = <0 x87e0 0 x05003880 0 x0 0 x30>;
ethernet-phy@0 {
...
reg = <0 >;
};
};
};
