Power management notifier struct. More...

#include <pm.h>

Data Fields
void(*	state_entry )(enum pm_state state)
	Application defined function for doing any target specific operations for power state entry.
void(*	state_exit )(enum pm_state state)
	Application defined function for doing any target specific operations for power state exit.

Detailed Description

Power management notifier struct.

This struct contains callbacks that are called when the target enters and exits power states.

As currently implemented the entry callback is invoked when transitioning from PM_STATE_ACTIVE to another state, and the exit callback is invoked when transitioning from a non-active state to PM_STATE_ACTIVE. This behavior may change in the future.

Note

These callbacks can be called from the ISR of the event that caused the kernel exit from idling.

It is not allowed to call pm_notifier_unregister or pm_notifier_register from these callbacks because they are called with the spin locked in those functions.
