Liam,

I have a rough peek into the git tree on opensource.wolfsonmicro.com,
find another PMIC framework, and here instead is a regulator framework,
looks like a simplified or dedicated one. What is their relationship?

For those PMIC that covers additional features, like
- usb vbus detection (or pull-up/pull-down)
- audio codec
- touch screen
- battery monitor/ fuel gauge
- battery charger
- possible many others

How do you plan to handle them?
