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". 17 18Example: 19 20/* Based on the configuration for a Raspberry Pi 3 B+ */ 21&usb { 22 usb-port@1 { 23 compatible = "usb424,2514"; 24 reg = <1>; 25 #address-cells = <1>; 26 #size-cells = <0>; 27 28 usb-port@1 { 29 compatible = "usb424,2514"; 30 reg = <1>; 31 #address-cells = <1>; 32 #size-cells = <0>; 33 34 ethernet: ethernet@1 { 35 compatible = "usb424,7800"; 36 reg = <1>; 37 local-mac-address = [ 00 11 22 33 44 55 ]; 38 39 mdio { 40 #address-cells = <0x1>; 41 #size-cells = <0x0>; 42 eth_phy: ethernet-phy@1 { 43 reg = <1>; 44 microchip,led-modes = < 45 LAN78XX_LINK_1000_ACTIVITY 46 LAN78XX_LINK_10_100_ACTIVITY 47 >; 48 }; 49 }; 50 }; 51 }; 52 }; 53}; 54
