+/**
+ * @class Configuration
+ *
+ * Configuration changes that should be applied to a device or regulator rail.
+ * These changes usually override hardware default settings.
+ *
+ * The most common configuration change is setting the output voltage for a
+ * regulator rail.  Other examples include modifying pgood thresholds and
+ * overcurrent settings.
+ *
+ * The configuration changes are applied during the boot before regulators are
+ * enabled.
+ *
+ * The configuration changes are applied by executing one or more actions.
+ *
+ * An output voltage value can be specified if necessary.  The value will be
+ * stored in the ActionEnvironment when the actions are executed.  Actions that
+ * require a volts value, such as PMBusWriteVoutCommandAction, can obtain it
+ * from the ActionEnvironment.
