 cpuidle driver initializes the cpuidle_device structure for each CPU device
 and registers with cpuidle using cpuidle_register_device.
 
+If all the idle states are the same, the wrapper function cpuidle_register
+could be used instead.
+
 It can also support the dynamic changes (like battery <-> AC), by using
 cpuidle_pause_and_lock, cpuidle_disable_device and cpuidle_enable_device,
 cpuidle_resume_and_unlock.
