We are talking about active states of a power domain here and
*performance* is the best word I got. And yes we can still have
frequency as a configurable here, just that current platforms don't
have it.

I was just pointing out a difference :)

Oh I meant that for converting general regulator only cases to OPP. No
firmware was involved there.
