Subject: [PATCH v5 1/9] remoteproc: Add new RPROC_DETACHED state
Date: Tue,  7 Jul 2020 15:00:06 -0600	[thread overview]
Message-ID: <20200707210014.927691-2-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <20200707210014.927691-1-mathieu.poirier@linaro.org>

Add a new RPROC_DETACHED state to take into account scenarios
where the remoteproc core needs to attach to a remote processor
that is booted by another entity.
