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 = <&reg_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>;
