1 Microchip LAN78xx Gigabit Ethernet controller
3 The LAN78XX devices are usually configured by programming their OTP or with
4 an external EEPROM, but some platforms (e.g. Raspberry Pi 3 B+) have neither.
5 The Device Tree properties, if present, override the OTP and EEPROM.
8 - compatible: Should be one of "usb424,7800", "usb424,7801" or "usb424,7850".
11 - local-mac-address: see ethernet.txt
12 - mac-address: see ethernet.txt
14 Optional properties of the embedded PHY:
15 - microchip,led-modes: a 0..4 element vector, with each element configuring
16 the operating mode of an LED. Omitted LEDs are turned off. Allowed values
17 are defined in "include/dt-bindings/net/microchip-lan78xx.h".
