Thanks for the feedback. Would you consider this (lifted from the Pi 3B+ Device
Tree)
a sufficient example?
&usb {
usb1@1 {
compatible = "usb424,2514";
reg = <1>;
#address-cells = <1>;
#size-cells = <0>;
usb1_1@1 {
compatible = "usb424,2514";
reg = <1>;
#address-cells = <1>;
#size-cells = <0>;
ethernet: usbether@1 {
compatible = "usb424,7800";
reg = <1>;
microchip,eee-enabled;
microchip,tx-lpi-timer = <600>; /*

/*

*/
microchip,led-modes = <1 6>;
};
};
};
};
