Subject: [PATCH v2 6/7] dt-bindings: net: realtek: Add property to configure LED mode
Date:   Wed,  3 Jul 2019 12:37:23 -0700
Message-Id: <20190703193724.246854-6-mka@chromium.org>

The LED behavior of some Realtek PHYs is configurable. Add the
property 'realtek,led-modes' to specify the configuration of the
LEDs.
