Subject: [PATCH v4 0/2] remoteproc: stm32: add support of detaching a remote processor

Update from V3:
add Reviewed by Rob Herring in patch 1/2 for bindings

This patchset is the stm32mp1 platform implementation of the detach operation
added in series [1].

On detach, the stm32 rproc driver sends a mailbox signal to the remote 
processor to inform it that it will be detached. 

Applied and tested on Bjorn's "for_next" branch (2b81aa17008e)

    detach
