3  * consumer.h -- SoC Regulator consumer support.
11  * A Power Management Regulator framework for SoC based devices.
12  * Features:-
19  *   Dynamic Regulator operating Mode Switching (DRMS) - allows regulators
47  * output load. This allows further system power savings by selecting the
54  * In order of power efficiency (least efficient at top).
61  *  NORMAL     Normal regulator power supply mode. Most drivers will
65  *             loads. Can be used for devices that have a low power
68  *             to handle fast load switching.
74  *             switching.
112  * struct pre_voltage_change_data - Data sent with PRE_VOLTAGE_CHANGE event
127  * struct regulator_bulk_data - Data used for bulk regulator operations.
