Subject: [PATCH 00/13] remoteproc: Add support for detaching from rproc

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 applcation processor power cycled while the remote processor is
still operating.

I have not tested the solution because of the work involved in getting
a new firmware image to support the feature.  I will do so once it is
determined that this is the right approach to follow.

Applies cleanly on rproc-next (62b8f9e99329)

Thanks,
