It was me. I thought you are talking about regulators and that is what is already managed, i.e. to work with or without regulators. > What if there is no OPP at all to use, then dev_pm_opp_set_rate() is > just a noop, right?

Yeah, that would be a problem and hacking the OPP core may not be the right solution :( -- viresh
