3  * consumer.h -- SoC Regulator consumer support.
12  * Features:-
14  *   o Operating mode control.
19  *   Dynamic Regulator operating Mode Switching (DRMS) - allows regulators
20  *   to use most efficient operating mode depending upon voltage and load and
25  *   idling. Regulator r has > 90% efficiency in NORMAL mode at loads > 100mA
27  *   efficiency in IDLE mode at loads < 10mA. Thus regulator r will operate
28  *   in normal mode for loads > 10mA and in IDLE mode for load <= 10mA.
47  * best (and most efficient) regulator mode for a desired load.
49  * Most drivers will only care about NORMAL. The modes below are generic and
55  *  Mode       Description
60  *  NORMAL     Normal regulator power supply mode. Most drivers will
61  *             use this mode.
63  *  IDLE       Regulator runs in a more efficient mode for light
65  *             requirement during periods of inactivity. This mode
66  *             may be more noisy than NORMAL and may not be able
69  *  STANDBY    Regulator runs in the most efficient mode for very
71  *             in a sleep/standby state. This mode is likely to be
76  * will only just support NORMAL.
143  * struct pre_voltage_change_data - Data sent with PRE_VOLTAGE_CHANGE event
158  * struct regulator_bulk_data - Data used for bulk regulator operations.
