| D | Kconfig | 8 devfreq, a generic DVFS framework can be registered for a device
9 in order to let the governor provided to devfreq choose an
14 notification to "nb", a notifier block, of devfreq.
18 determined by the single device's state, an instance of devfreq
21 to a device by 1-to-1. The device registering devfreq takes the
24 given to devfreq.
26 When OPP is used with the devfreq device, it is recommended to
27 register devfreq's nb to the OPP's notifier head. If OPP is
28 used with the devfreq device, you may use OPP helper
29 functions defined in devfreq.h.
