Subject: [PATCH v4 03/11] remoteproc: stm32: Decouple rproc from DT parsing
Date: Mon,  1 Jun 2020 11:55:44 -0600	[thread overview]
Message-ID: <20200601175552.22286-4-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <20200601175552.22286-1-mathieu.poirier@linaro.org>

Remove the remote processor from the process of parsing the device tree
since (1) there is no correlation between them and (2) to use the
information that was gathered to make a decision on whether to
synchronise with the M4 or not.
