1 | Regulator Driver Interface | ||
2 | ========================== | ||
3 | |||
4 | The regulator driver interface is relatively simple and designed to allow | ||
5 | regulator drivers to register their services with the core framework. | ||
6 | |||
7 | |||
8 | Registration | ||
9 | ============ | ||
10 | |||
11 | Drivers can register a regulator by calling :- | ||
12 | |||
13 | struct regulator_dev *regulator_register(struct regulator_desc *regulator_desc, | ||
14 | void *reg_data); | ||
15 | |||
16 | This will register the regulators capabilities and operations the regulator | ||
17 | core. The core does not touch reg_data (private to regulator driver). | ||
18 | |||
19 | Regulators can be unregistered by calling :- | ||
20 | |||
21 | void regulator_unregister(struct regulator_dev *rdev); | ||
22 | |||
23 | |||
24 | Regulator Events | ||
25 | ================ | ||
26 | Regulators can send events (e.g. over temp, under voltage, etc) to consumer | ||
27 | drivers by calling :- | ||
28 | |||
29 | int regulator_notifier_call_chain(struct regulator_dev *rdev, | ||
30 | unsigned long event, void *data); | ||
