Subject[PATCH v6 00/16] remoteproc: Add support for detaching a remote processor
Date
Following the work done here [1], 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.

Modifications for this revision are detailed in the changelog of each patch
but the main difference is that going from RPROC_RUNNING -> RPROC_DETACHED
is no longer supported to avoid dealing tricky resource table issues.

Applies cleanly on rproc-next (e8b4e9a21af7). I will rebase on 5.12-rc1 when it
comes out next week.

Thanks,
Mathieu
