No, he misunderstood it. He was saying that the domain needs a performance-index and the device needs freq-scaling, how do we do that? He thought that there will be just one OPP table for the device here, but we will actually have two and that would work.

Yeah, I have some doubts on how we are going to implement that and looking for more input from him.
