[net-next PATCH v6 10/16] dt-bindings: leds: Document support for generic ethernet LEDs

[Christian Marangi]

Add documentation for support of generic ethernet LEDs.
These LEDs are ethernet port LED and are controllable by the ethernet
controller or the ethernet PHY.

A port may expose multiple LEDs and reg is used to provide an index to
differentiate them.
Ethernet port LEDs follow generic LED implementation.

+description:
+  Bindings for the LEDs present in ethernet port and controllable by
+  the ethernet controller or the ethernet PHY regs.
+
+  These LEDs provide the same feature of a normal LED and follow
+  the same LED definitions.
+
+  An ethernet port may expose multiple LEDs, reg binding is used to
+  differentiate them.

+  '#address-cells':
+    const: 1

+        description:
+          This define the LED index in the PHY or the MAC. It's really
+          driver dependent and required for ports that define multiple
+          LED for the same port.
