From: Rafał Miłecki <rafal at milecki.pl>

Some LEDs are designed to represent a state of another device. That may
be USB port, Ethernet interface, CPU, hard drive and more.

We already have support for LEDs that are designed to indicate USB port
(e.g. light on when USB device gets connected). There is DT binding for
that and Linux implementation in USB trigger.

This patchset adds support for describing LEDs that should react to
Ethernet interface status. That is commonly used in routers. They often
have LED to display state and activity of selected physical port. It's
also common to have multiple LEDs, each reacting to a specific link
speed.

Patch 5/5 is proof of concept and is not meant to be applied yet.

Rafał Miłecki (5):
  dt-bindings: net: add bitfield defines for Ethernet speeds
  dt-bindings: net: allow Ethernet devices as LED triggers
  dt-bindings: leds: add Ethernet triggered LEDs to example
  ARM: dts: BCM5301X: Add triggers for Luxul XWR-1200 network LEDs
  leds: trigger: netdev: support DT "trigger-sources" property
