Subject: [PATCH v7 03/17] remoteproc: Add new RPROC_ATTACHED state
Date: Wed, 10 Mar 2021 14:10:11 -0700	[thread overview]
Message-ID: <20210310211025.1084636-4-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <20210310211025.1084636-1-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.
