LG		 9 * Regulator Consumer Interface.
10 *
11 * A Power Management Regulator framework for SoC based devices.
12 * Features:-
13 * o Voltage and current level control.
14 * o Operating mode control.
15 * o Regulator status.
16 * o sysfs entries for showing client devices and status
17 *
18 * EXPERIMENTAL FEATURES:
19 * Dynamic Regulator operating Mode Switching (DRMS) - allows regulators
20 * to use most efficient operating mode depending upon voltage and load and
21 * is transparent to client drivers.
22 *
23 * e.g. Devices x,y,z share regulator r. Device x and y draw 20mA each during
24 * IO and 1mA at idle. Device z draws 100mA when under load and 5mA when
25 * idling. Regulator r has > 90% efficiency in NORMAL mode at loads > 100mA
26 * but this drops rapidly to 60% when below 100mA. Regulator r has > 90%
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.

43 * Regulator operating modes.
44 *
45 * Regulators can run in a variety of different operating modes depending on
46 * output load. This allows further system power savings by selecting the
47 * best (and most efficient) regulator mode for a desired load.
48 *
49 * Most drivers will only care about NORMAL. The modes below are generic and
50 * will probably not match the naming convention of your regulator data sheet
51 * but should match the use cases in the datasheet.
52 *
53 * In order of power efficiency (least efficient at top).
54 *
55 * Mode Description
56 * FAST Regulator can handle fast changes in it's load.
57 * e.g. useful in CPU voltage & frequency scaling where
58 * load can quickly increase with CPU frequency increases.
59 *
60 * NORMAL Normal regulator power supply mode. Most drivers will
61 * use this mode.
62 *
63 * IDLE Regulator runs in a more efficient mode for light
64 * loads. Can be used for devices that have a low power
65 * requirement during periods of inactivity. This mode
66 * may be more noisy than NORMAL and may not be able
67 * to handle fast load switching.
68 *
69 * STANDBY Regulator runs in the most efficient mode for very
70 * light loads. Can be used by devices when they are
71 * in a sleep/standby state. This mode is likely to be
72 * the most noisy and may not be able to handle fast load
73 * switching.
74 *
75 * NOTE: Most regulators will only support a subset of these modes. Some
76 * will only just support NORMAL.
77 *
78 * These modes can be OR'ed together to make up a mask of valid register modes.
