Implement new property arm,no-completion-irq, which sets all SCMI operation into poll mode. This is meant to work around uncooperative SCP implementations, which do not generate completion interrupts. This applies to mbox/shmem based implementations. With this property set, such implementations which do not generate interrupts can be interacted with, until they are fixed to generate interrupts properly.

LGTM. Reviewed-by: Cristian Marussi <cristian.marussi@arm.com>Is there anything left to do with these patches, or can this now be picked up ?Would love to see this going in. I also work with the firmware which needs this functionality.
I have not seen anymore push back around this, but I think it was late anyway to be picked up as an update for this cycle given that it was already -rc6 when the last series landed...so I guess it could picked up now for the next cycle ...but I have not checked with Sudeep.. Thanks, Cristian
