Subject: [PATCH v4 01/17] dt-bindings: remoteproc: Add bindind to support autonomous processors
Date: Fri, 18 Dec 2020 10:32:12 -0700 [thread overview]
Message-ID: <20201218173228.2277032-2-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <20201218173228.2277032-1-mathieu.poirier@linaro.org>
This patch adds a binding to guide the remoteproc core on how to deal with
remote processors in two cases:
1) When an application holding a reference to a remote processor character
device interface crashes.
2) when the platform driver for a remote processor is removed.
In both cases if "autonomous-on-core-reboot" is specified in the remote
processor DT node, the remoteproc core will detach the remote processor
rather than switching it off.
