Subject: [PATCH 2/6] rpmsg: glink: Store edge name for glink device
Date: Mon, 18 Dec 2017 14:02:10 -0800 [thread overview]
Message-ID: <1513634534-22861-3-git-send-email-clew@codeaurora.org> (raw)
In-Reply-To: <1513634534-22861-1-git-send-email-clew@codeaurora.org>
Channels may need to identify the edge their channel was probed for.
Store the edge name by reading the label property from device tree or
default to the node name.
