Subject: [PATCH V8 11/23] coresight: etm3x: consolidating initial config
Date: Thu, 14 Jan 2016 14:46:05 -0700 [thread overview]
Message-ID: <1452807977-8069-12-git-send-email-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <1452807977-8069-1-git-send-email-mathieu.poirier@linaro.org>
There is really no point in having two functions to take care
of doing the initial tracer configuration. As such moving
everything to 'etm_set_default()'.
