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