Why limit it to just voltage levels. As I suggested earlier, I think this should use OPPs. Remember that a PM domain is not limited to a hardware power domain, but is just a grouping mechanism for devices that share some PM properties. As mentioned by Geert, this can also be a clock domain, where frequencies would make sense as well. One can imagine using this type of PM domain to manage an interconnect/bus which has scalable voltage/frequencies as well. Kevin
