+ *
+ * EXPERIMENTAL FEATURES:
+ *   Dynamic Regulator operating Mode Switching (DRMS) - allows regulators
+ *   to use most efficient operating mode depending upon voltage and load and
+ *   is transparent to client drivers.
+ *
+ *   e.g. Devices x,y,z share regulator r. Device x and y draw 20mA each during
+ *   IO and 1mA at idle. Device z draws 100mA when under load and 5mA when
+ *   idling. Regulator r has > 90% efficiency in NORMAL mode at loads > 100mA
+ *   but this drops rapidly to 60% when below 100mA. Regulator r has > 90%
+ *   efficiency in IDLE mode at loads < 10mA. Thus regulator r will operate
+ *   in normal mode for loads > 10mA and in IDLE mode for load <= 10mA.

+ * Regulator operating modes.
+ *
+ * Regulators can run in a variety of different operating modes depending on
+ * output load. This allows further system power savings by selecting the
+ * best (and most efficient) regulator mode for a desired load.
+ *
+ * Most drivers will only care about NORMAL. The modes below are generic and
+ * will probably not match the naming convention of your regulator data sheet
+ * but should match the use cases in the datasheet.
+ *
+ * In order of power efficiency (least efficient at top).
+ *
+ *  Mode       Description
+ *  FAST       Regulator can handle fast changes in it's load.
+ *             e.g. useful in CPU voltage & frequency scaling where
+ *             load can quickly increase with CPU frequency increases.
+ *
+ *  NORMAL     Normal regulator power supply mode. Most drivers will
+ *             use this mode.
+ *
+ *  IDLE       Regulator runs in a more efficient mode for light
+ *             loads. Can be used for devices that have a low power
+ *             requirement during periods of inactivity. This mode
+ *             may be more noisy than NORMAL and may not be able
+ *             to handle fast load switching.
+ *
+ *  STANDBY    Regulator runs in the most efficient mode for very
+ *             light loads. Can be used by devices when they are
+ *             in a sleep/standby state. This mode is likely to be
+ *             the most noisy and may not be able to handle fast load
+ *             switching.
+ *
+ * NOTE: Most regulators will only support a subset of these modes. Some
+ * will only just support NORMAL.
+ *
+ * These modes can be OR'ed together to make up a mask of valid register modes.
