These one we need as ALSA-controls. They are parameters that we can tune during runtime and are not hard-wired in any way.
This seems incredibly surprising - are you sure the configuration isn't simply a case of enabling and disabling the charge pump voltage scaling?
Well, yes. One of the control enables/disables the ability to use another charge-pump voltage when the signal gets over a certain threshold. The other parameters are tuning of this theshold and responsiveness. This feature can be changed during runtime depending of quality vs. powersaving needs.
