=====================================================================
If your board that GMAC2 connects with Airoha EN8811H, please change
the eth node as following.
ð {
...
gmac1: mac@1 {
compatible = "mediatek,eth-mac";
reg = <1>;
phy-mode = "2500base-x";
phy-handle = <&phy15>;
};
mdio: mdio-bus {
#address-cells = <1>;
#size-cells = <0>;
phy15: phy@15 {
compatible = "ethernet-phy-id03a2.a411";
reg = <15>;
phy-mode = "2500base-x";
full-duplex;
pause;
};
...
};
};
=====================================================================
In addition, if EN8811H connects with a RESET GPIO, please check the
GPIO number, and then add reset-gpio related definition to above phy
node.
=====================================================================
reset-gpios = <&gpio 6 1>;
reset-assert-us = <10000>;
reset-deassert-us = <10000>;
=====================================================================
If without this patch, kernel cannot load up-to-date PHY driver
for the Airoha EN8811H.
