+ Say yes here if you want to use the power resources on the
+ TWL4030 family chips. Most of these resources are regulators,
+ which have a separate driver; some are control signals, such

+
+ This driver uses board-specific data to initialize the resources
+ and load scripts controling which resources are switched off/on
