But then why do we need a node here at all? Can't you assume reboot support for TI-SCI firmware (i.e. based on the parent node). Then you don't need a DT update to add the feature. Rob

Might even have been better that way, for now I'm trying to be consistent with what is already here (child node per service provided, even though the services are always the same). Andrew > Rob
