Hi. The mdio interface is shared between gem0 and gem3. The device tree should look like below. We will soon release petalinux BSPs based on 2020.1. Please contact our support for a preliminary release. Greets

&gem0 {
    status = "okay";
    /delete-property/ local-mac-address;
    phy-mode = "rgmii-id";
    phy-handle = <&phy0>;
    phy0: phy@3 {
        reg = <3>;

        txc-skew-ps = <1800>;
        txen-skew-ps = <420>;

        txd0-skew-ps = <420>;
        txd1-skew-ps = <420>;
        txd2-skew-ps = <420>;
        txd3-skew-ps = <420>;

        rxc-skew-ps = <900>;
        rxdv-skew-ps = <420>;

        rxd0-skew-ps = <420>;
        rxd1-skew-ps = <420>;
        rxd2-skew-ps = <420>;
        rxd3-skew-ps = <420>;       
    };
    phy1: phy@7 {
        reg = <7>;

        txc-skew-ps = <1800>;
        txen-skew-ps = <420>;

        txd0-skew-ps = <420>;
        txd1-skew-ps = <420>;
        txd2-skew-ps = <420>;
        txd3-skew-ps = <420>;

        rxc-skew-ps = <900>;
        rxdv-skew-ps = <420>;

        rxd0-skew-ps = <420>;
        rxd1-skew-ps = <420>;
        rxd2-skew-ps = <420>;
        rxd3-skew-ps = <420>;       
    };
};
