Subject: [PATCH v7 00/17] remoteproc: Add support for detaching a remote processor
Date: Wed, 10 Mar 2021 14:10:08 -0700	[thread overview]
Message-ID: <20210310211025.1084636-1-mathieu.poirier@linaro.org> (raw)

This set provides support for the remoteproc core to release resources
associated with a remote processor without having to switch it off. That
way a platform driver can be removed or the application processor power
cycled while the remote processor is still operating.

The main difference in this revision is patch 11/16 (in V6).  It was split
split in two part in order to simplify handling of the resource table when
the remote processor is detached or stopped.  Other modifications are
detailed in the changelog of each patch.

Applies cleanly on v5.12-rc2.

Thanks,
Mathieu
