Subject: [PATCH v3 2/6] rpmsg: glink: Store edge name for glink device
Date: Thu, 26 Apr 2018 15:59:01 -0700	[thread overview]
Message-ID: <1524783545-21951-3-git-send-email-clew@codeaurora.org> (raw)
In-Reply-To: <1524783545-21951-1-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.
