Detailed Description

System power lock structure.

The power lock structure represents a request for a power level the system should be kept on while CPU is in idle.

The structure must be instantiated in the RAM memory using one of PM_LOCK_INIT() or DECLARE_PM_LOCK(). Note that the power request is not active unless PM_LOCK() is called for it.
