How you actually pass the vote to the underlying hardware, RPMh or GMU, is irrelevant to the whole thing. What is important is how we describe that in DT and how we represent the whole thing. We have chosen genpd + OPP to do this and same should be used by you as well. Another benefit is that the genpd core will do vote aggregation for you here. -- viresh
