Subject: [PATCH v6 03/16] remoteproc: Add new RPROC_ATTACHED state
Date: Tue, 23 Feb 2021 16:35:02 -0700	[thread overview]
Message-ID: <20210223233515.3468677-4-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <20210223233515.3468677-1-mathieu.poirier@linaro.org>

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