The current expectation is that a consumer that really needs a voltage
setting will have exclusive use of the regulator and won't share it with
other consumers. There was some support for combining constraints from
multiple consumers originally but it got removed due to requests from
David Brownell (there's not actually much demand for this feature
anyway, finding devices which support but do not required DVS is
actually quite hard and generally the power requirments for shared rails
get fixed at hardware build tiem).
