Yes, once the control goes off chip the regulator framework definitely makes sense. It's only for things on the same die where there may be less of a clear separation for the power supplies and where there's likely to not be much more than simple power switching that it *might* be worth doing something custom which more directly represents what's going on. _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
