This is already done in the Lamobo R1 DTS file so it would be nice not to break this use case:
&gmac { pinctrl-names = "default"; pinctrl-0 = <&gmac_pins_rgmii_a>; phy-mode = "rgmii"; phy-supply = <®_gmac_3v3>; status = "okay";
fixed-link { speed = <1000>; full-duplex; };
mdio { compatible = "snps,dwmac-mdio"; #address-cells = <1>; #size-cells = <0>;
switch: ethernet-switch@1e { compatible = "brcm,bcm53125"; reg = <30>; #address-cells = <1>; #size-cells = <0>;
