We can't do this - current doesn't map 1:1 through a regulator, the power consumption will map through but obviously there's a voltage change involved and the regulators will not be 100% efficient so there will also be some overhead from the chipld regulator. The child regulator needs to do the mapping in a regulator specific fashion.
