From 57b6c752c5c05a1f38eb6da9f1618f1b000e1f51 Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Mon, 17 Apr 2023 17:17:32 +0200 Subject: [PATCH] dt-bindings: net: ethernet-controller: Document support for LEDs node Document support for LEDs node in ethernet-controller. Ethernet Controller may support different LEDs that can be configured for different operation like blinking on traffic event or port link. Also add some Documentation to describe the difference of these nodes compared to PHY LEDs, since ethernet-controller LEDs are controllable by the ethernet controller regs and the possible intergated PHY doesn't have control on them.
