13 notification to "nb", a notifier block, of devfreq.
17 determined by the single device's state, an instance of devfreq
20 to a device by 1-to-1. The device registering devfreq takes the
23 given to devfreq.
25 When OPP is used with the devfreq device, it is recommended to
26 register devfreq's nb to the OPP's notifier head. If OPP is
27 used with the devfreq device, you may use OPP helper
28 functions defined in devfreq.h.
