 1Microchip LAN78xx Gigabit Ethernet controller
 2
 3The LAN78XX devices are usually configured by programming their OTP or with
 4an 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 properties
11defined in ethernet.txt.
12
13Optional properties of the embedded PHY:
14- microchip,led-modes: a 0..4 element vector, with each element configuring
15  the operating mode of an LED. Omitted LEDs are turned off. Allowed values
16  are defined in "include/dt-bindings/net/microchip-lan78xx.h".
