Subject: [PATCH v2 13/17] remoteproc: Introducting new functions to start and stop an MCU
Date: Tue, 24 Mar 2020 15:45:59 -0600	[thread overview]
Message-ID: <20200324214603.14979-14-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <20200324214603.14979-1-mathieu.poirier@linaro.org>

Add new functions to replace direct calling of rproc->ops->start() and
rproc->ops->stop().  That way different behaviour can be played out
when booting an MCU or synchronising with it.
