As of_get_mac_address now supports NVMEM under the hood, we need to update the bindings documentation with the new nvmem-cell* properties, which would mean copy&pasting a lot of redundant information to every binding documentation currently referencing some of the MAC address properties. So I've just removed all the references to the optional MAC address properties and replaced them with the small note referencing net/ethernet.txt file.

Microchip LAN78xx Gigabit Ethernet controller
|
|
|
|
The LAN78XX devices are usually configured by programming their OTP or with
|
|
an external EEPROM, but some platforms (e.g. Raspberry Pi 3 B+) have neither.
|
|
The Device Tree properties, if present, override the OTP and EEPROM.
|
|
|
|
Required properties:
|
|
- compatible: Should be one of "usb424,7800", "usb424,7801" or "usb424,7850".
|
|
|
|
The MAC address will be determined using the optional properties
|
|
defined in ethernet.txt.
|
|
|
|
Optional properties of the embedded PHY:
|
|
- microchip,led-modes: a 0..4 element vector, with each element configuring
|
|
the operating mode of an LED. Omitted LEDs are turned off. Allowed values
|
|
are defined in "include/dt-bindings/net/microchip-lan78xx.h".
|
|
|
|
Example:
|
|
|
|
/* Based on the configuration for a Raspberry Pi 3 B+ */
|
|
&usb {
|
|
usb-port@1 {
|
|
compatible = "usb424,2514";
|
|
reg = <1>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
|
|
usb-port@1 {
|
|
compatible = "usb424,2514";
|
|
reg = <1>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
|
|
ethernet: ethernet@1 {
|
|
compatible = "usb424,7800";
|
|
reg = <1>;
|
|
local-mac-address = [ 00 11 22 33 44 55 ];
|
|
|
|
mdio {
|
|
#address-cells = <0x1>;
|
|
#size-cells = <0x0>;

reg = <1>;
