Drivers can register a regulator by calling :-
struct regulator_dev *regulator_register(struct regulator_desc *regulator_desc,
- struct device *dev, struct regulator_init_data *init_data,
- void *driver_data, struct device_node *of_node);
+ const struct regulator_config *config);
This will register the regulators capabilities and operations to the regulator
core.
