1Microchip LAN78xx Gigabit Ethernet controller2 3The LAN78XX devices are usually configured by programming their OTP or with4an external EEPROM, but some platforms (e.g. Raspberry Pi 3 B+) have neither.5The Device Tree properties, if present, override the OTP and EEPROM.6 7Required properties:8- compatible: Should be one of "usb424,7800", "usb424,7801" or "usb424,7850".9 10The MAC address will be determined using the optional properties11defined in ethernet.txt.12 13Optional properties of the embedded PHY:14- microchip,led-modes: a 0..4 element vector, with each element configuring15 the operating mode of an LED.
