Current version of rtl8366-smi module only supports Realtek switch
managment via two gpio lines. This adds Realtek switch
management via mii_bus. Tested on a Tp-link Archer C2 v1 (Mediatek
SoC mt7620a based)
dts-file configuration should look like this:
rtl8367rb {
compatible = "realtek,rtl8367b";
realtek,extif1 = <1 0 1 1 1 1 1 1 2>;
mii-bus = <&mdio0>;
};
ðernet {
status = "okay";
mtd-mac-address = <&rom 0xf100>;
pinctrl-names = "default";
pinctrl-0 = <&rgmii1_pins &rgmii2_pins &mdio_pins>;
port@5 {
status = "okay";
mediatek,fixed-link = <1000 1 1 1>;
phy-mode = "rgmii";
};
mdio0: mdio-bus {
status = "okay";
};
};
