The core does not touch reg_data (private to regulator driver). + +Regulators can be unregistered by calling :- + +void regulator_unregister(struct regulator_dev *rdev); + + +Regulator Events +================ +Regulators can send events (e.g. over temp, under voltage, etc) to consumer +drivers by calling :- + +int regulator_notifier_call_chain(struct regulator_dev *rdev, + unsigned long event, void *data);
