Sorry about that, I did exactly opposite of this earlier :(

About putting those stuff into regulator driver, I think you mean creating a "virtual regulator device" and put all the voltage controlling complex into the driver, right? Maybe it's a good idea in this case, but I am sure if this kind of virtual regulator is acceptable.
@Mark: Is this allowed to create virtual regulator for a CPU ?
I don't really know what the above means or what problem it's supposed to solve.
On mediatek platform, they need to configure two regulators in order to change DVFS state of the big cluster. The generic cpufreq-dt driver and earlier OPP bindings have support for a single regulator only and so what Pi-cheng tried to do is, - Configure one of the regulators using cpufreq-dt - And other one using cpufreq frequency change notifiers
This looks awkward..
What I suggested was to create another virtual regulator for CPU which will eventually configure both the regulators. And so the question that such virtual regulators are allowed or not.
