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>; /* non-aggressive*/ /* * led0 = 1:link1000/activity * led1 = 6:link10/100/activity */ microchip,led-modes = <1 6>; }; }; }; };
Phil
