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. / #ifndef __LINUX_REGULATOR_CONSUMER_H_ #define __LINUX_REGULATOR_CONSUMER_H_ #include <linux/err.h> struct device; struct notifier_block; struct regmap; / * 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. / #define REGULATOR_MODE_INVALID 0x0 #define REGULATOR_MODE_FAST 0x1 #define REGULATOR_MODE_NORMAL 0x2 #define REGULATOR_MODE_IDLE 0x4 #define REGULATOR_MODE_STANDBY 0x8 / * Regulator notifier events. * * UNDER_VOLTAGE Regulator output is under voltage. * OVER_CURRENT Regulator output current is too high. * REGULATION_OUT Regulator output is out of regulation. * FAIL Regulator output has failed. * OVER_TEMP Regulator over temp. * FORCE_DISABLE Regulator forcibly shut down by software. * VOLTAGE_CHANGE Regulator voltage changed. * Data passed is old voltage cast to (void ).
