1 Regulator Driver Interface
2 ==========================
4 The regulator driver interface is relatively simple and designed to allow
5 regulator drivers to register their services with the core framework.
8 Registration
9 ============
11 Drivers can register a regulator by calling :-
13 struct regulator_dev *regulator_register(struct regulator_desc *regulator_desc,
14         struct device *dev, struct regulator_init_data *init_data,
15         void *driver_data);
17 This will register the regulators capabilities and operations to the regulator
18 core.
20 Regulators can be unregistered by calling :-
22 void regulator_unregister(struct regulator_dev *rdev);
25 Regulator Events
26 ================
27 Regulators can send events (e.g. over temp, under voltage, etc) to consumer
28 drivers by calling :-
30 int regulator_notifier_call_chain(struct regulator_dev *rdev,
31                                   unsigned long event, void *data);
