Properties for an MDIO bus multiplexer found in Broadcom iProc based SoCs. |
|
|
|
This MDIO bus multiplexer defines buses that could be internal as well as |
|
external to SoCs and could accept MDIO transaction compatible to C-22 or |
|
C-45 Clause. When child bus is selected, one needs to select these two |
|
properties as well to generate desired MDIO transaction on appropriate bus. |
|
|
|
Required properties in addition to the generic multiplexer properties: |
|
|
|
MDIO multiplexer node: |
|
- compatible: brcm,mdio-mux-iproc. |
|
|
|
Every non-ethernet PHY requires a compatible so that it could be probed based |
|
on this compatible string. |
|
|
|
Optional properties: |
|
- clocks: phandle of the core clock which drives the mdio block. |
|
|
|
Additional information regarding generic multiplexer properties can be found |
|
at- Documentation/devicetree/bindings/net/mdio-mux.yaml |
|
|
|
|
|
for example: |
|
mdio_mux_iproc: mdio-mux@66020000 { |
|
compatible = "brcm,mdio-mux-iproc"; |
|
reg = <0x66020000 0x250>; |
|
#address-cells = <1>; |
|
#size-cells = <0>; |
|
|
|
mdio@0 { |
|
reg = <0x0>; |
|
#address-cells = <1>; |
|
#size-cells = <0>; |
|
|
|
pci_phy0: pci-phy@0 { |
|
compatible = "brcm,ns2-pcie-phy"; |
|
reg = <0x0>; |
|
#phy-cells = <0>; |
|
}; |
|
}; |
|
|
|
mdio@7 { |
|
reg = <0x7>; |
|
#address-cells = <1>; |
|
#size-cells = <0>; |
|
|
|
pci_phy1: pci-phy@0 { |
|
compatible = "brcm,ns2-pcie-phy"; |
|
reg = <0x0>; |
|
#phy-cells = <0>; |
|
}; |
|
}; |
|
mdio@10 { |
|
reg = <0x10>; |
|
#address-cells = <1>; |
|
#size-cells = <0>; |
|
|
|
gphy0: eth-phy@10 { |
|
reg = <0x10>; |
|
}; |
|
}; |
|
};
