I'm not entirely sure why/how it works either and waiting for a answer from someone with a more knowledge about ramips.

I suspect it is copy/paste from MT7620a_MT7610e.dts, which has a has an additional/extra (?) phy attached to switch port4:


&ethernet {
        status = "okay";
        pinctrl-names = "default";
        pinctrl-0 = ;
        mediatek,portmap = "llllw";
};

&gsw {
        mediatek,port4 = "ephy";
};
