10cpuidle driver hooks into the cpuidle infrastructure and handles the
11architecture/platform dependent part of CPU idle states. Driver
12provides the platform idle state detection capability and also
13has mechanisms in place to support actual entry-exit into CPU idle states.
14
15cpuidle driver initializes the cpuidle_device structure for each CPU device
16and registers with cpuidle using cpuidle_register_device.
17
18It can also support the dynamic changes (like battery <-> AC), by using
19cpuidle_pause_and_lock, cpuidle_disable_device and cpuidle_enable_device,
20cpuidle_resume_and_unlock.
