This state is commonly used by * hogs to configure muxing and pins at boot , and also as a state * to go into when returning from sleep and idle in * . pm_runtime_resume ( ) or ordinary . resume ( ) for example . * @ PINCTRL_STATE_INIT : normally the pinctrl will be set to " default " * before the driver ' s probe ( ) function is called . There are some * drivers where that is not appropriate becausing doing so would * glitch the pins . In those cases you can add an " init " pinctrl * which is the state of the pins before drive probe . After probe * if the pins are still in " init " state they ' ll be moved to * " default " . * @ PINCTRL_STATE_IDLE : the state the pinctrl handle shall be put into * when the pins are idle . This is a state where the system is relaxed * but not fully sleeping - some power may be on but clocks gated for * example . Could typically be set from a pm_runtime_suspend ( ) or * pm_runtime_idle ( ) operation . * @ PINCTRL_STATE_SLEEP : the state the pinctrl handle shall be put into * when the pins are sleeping . This is a state where the system is in * its lowest sleep state . Could typically be set from an * ordinary . suspend ( ) function . #define PINCTRL_STATE_DEFAULT "default" #define PINCTRL_STATE_INIT "init" #define PINCTRL_STATE_IDLE "idle" #define PINCTRL_STATE_SLEEP "sleep" #endif /* __LINUX_PINCTRL_PINCTRL_STATE_H */
