Subject: [PATCH 2/4] coresight: replicator: Add new device id for static replicator
Date: Thu, 2 May 2019 10:54:03 -0600 [thread overview]
Message-ID: <20190502165405.31573-3-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <20190502165405.31573-1-mathieu.poirier@linaro.org>
From: Leo Yan <leo.yan@linaro.org>
This patch adds a device id for the new static replicator compatible
string; it changes the driver name from "coresight-replicator" to
"coresight-static-replicator" as well.
This patch also gives warning when use the replicator obsolete DT
binding.
