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                                          const struct regulator_config *config);
16 This will register the regulator's capabilities and operations to the regulator
17 core.
19 Regulators can be unregistered by calling :-
21 void regulator_unregister(struct regulator_dev *rdev);
24 Regulator Events
25 ================
26 Regulators can send events (e.g. overtemperature, undervoltage, etc) to
27 consumer drivers by calling :-
29 int regulator_notifier_call_chain(struct regulator_dev *rdev,
30                                   unsigned long event, void *data);
