11  * A Power Management Regulator framework for SoC based devices.

19  *   Dynamic Regulator operating Mode Switching (DRMS) - allows regulators
25  *   idling. Regulator r has > 90% efficiency in NORMAL mode at loads > 100mA
28  *   in normal mode for loads > 10mA and in IDLE mode for load <= 10mA.
47  * output load. This allows further system power savings by selecting the
50  * Most drivers will only care about NORMAL. The modes below are generic and
54  * In order of power efficiency (least efficient at top).
61  *  NORMAL     Normal regulator power supply mode. Most drivers will

112  * struct pre_voltage_change_data - Data sent with PRE_VOLTAGE_CHANGE event
127  * struct regulator_bulk_data - Data used for bulk regulator operations.
