Subject: [PATCH 04/11] dt-binding: remoteproc: wcnss: Allow describing smd edge
Date: Wed, 19 Oct 2016 19:40:05 -0700 [thread overview]
Message-ID: <1476931212-1806-5-git-send-email-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <1476931212-1806-1-git-send-email-bjorn.andersson@linaro.org>
Allow the associated smd edge to be described within the wcnss
remoteproc node. This creates a bond between the remoteproc and the
associated smd channels and devices, showing the interaction between the
two parts and provides both a natural reference to the other.
