Hi Rob

Thank you for first review

mux and conf are used to match subnodes see example for mdio0_pins

mdio0_pins: mdio0-pins {
  mux {
    function = "eth";
    groups = "mdc_mdio0";
  };

  conf {
    pins = "SMI_0_MDC", "SMI_0_MDIO";
    drive-strength = <MTK_DRIVE_8mA>;
  };
};

This is same as done for previous SoC like mt7986.
