Thank you for reminding me. But we shouldn't use this for CPU devices as the CPU device doesn't get bound to a driver, it is rather a fake platform device which gets the cpufreq drivers probed. > > I'd also like to see a devm helper for > dev_pm_opp_register_set_opp_helper(), which should become useful for > Tegra drivers sometime soon.

You can't put so many names in the cclist, we are getting failure messages while replying to your patches now. Put all people you want to inform in the bcc section and only the important ones in to/cc list.
