[PATCH net-next v4 8/8] arm: boot: dts: mvebu: linksys-mamba: Add Ethernet LEDs

Andrew Lunn
2024-04-06T20:14:20Z

List the front panel Ethernet LEDs in the switch section of the
device tree. They can then be controlled via /sys/class/led/

The node contains a label property to influence the name of the LED.
Without it, all the LEDs get the name lan:white, which classes, and so
some get a number appended. lan:white_1, lan:white_2, etc. Using the
label the LEDs are named lan1:front, lan2:front, lan3:front, where
lanX indicates the interface name, and front indicates they are on the
front of the box.
