The RPMH_VREG macro expects _supply_name so what should I put there instead?

Problem is I do not know which types those regulators are, e.g. pldo or nldo. 
The ones I described are experimentally verified because the wrong configuration 
makes the driver probe fail.
So I can't really put anything there, unless there's another way to do this.
