Would the coupled regulator binding work in this case? Rob

Right, especially given that if people can't find the documentation for driver binding changes that's likely to be one of the first compliants. > > +- qcom,saw-leader: > > + Usage: optional > > + Value type: <boo> > > + Description: SAW controlled gang leader.

Someone would need to get the code working first though depending on what the hardware does that might not be the right thing. It's fairly common to have hardware support for grouping multiple physical regulators together into a single supply in order to provide more current with all the control being done from one of the regulators.
