From be33c28fadc5442d30f0f9dc08f6b4e3664b12f7 Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Wed, 19 Oct 2016 19:40:05 -0700 Subject: [PATCH] dt-binding: remoteproc: wcnss: Allow describing smd edge 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.
