   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.

   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         struct device *dev, struct regulator_init_data *init_data,
  15         void *driver_data);
  16
  17 This will register the regulators capabilities and operations to the regulator
  18 core.
  19
  20 Regulators can be unregistered by calling :-
  21
  22 void regulator_unregister(struct regulator_dev *rdev);
  23
  24
  25 Regulator Events
  26 ================
  27 Regulators can send events (e.g. over temp, under voltage, etc) to consumer
  28 drivers by calling :-
  29
  30 int regulator_notifier_call_chain(struct regulator_dev *rdev,
  31                                   unsigned long event, void *data);
