==========================
Regulator Driver Interface
==========================

The regulator driver interface is relatively simple and designed to allow
regulator drivers to register their services with the core framework.


Registration
============

Drivers can register a regulator by calling::

  struct regulator_dev *regulator_register(struct regulator_desc *regulator_desc,
					   const struct regulator_config *config);

This will register the regulator's capabilities and operations to the regulator
core.

Regulators can be unregistered by calling::

  void regulator_unregister(struct regulator_dev *rdev);


Regulator Events
================

Regulators can send events (e.g. overtemperature, undervoltage, etc) to
consumer drivers by calling::

  int regulator_notifier_call_chain(struct regulator_dev *rdev,
				    unsigned long event, void *data);
