| D | Kconfig | 5 devfreq, a generic DVFS framework can be registered for a device
6 in order to let the governor provided to devfreq choose an
11 notification to "nb", a notifier block, of devfreq.
15 determined by the single device's state, an instance of devfreq
18 to a device by 1-to-1. The device registering devfreq takes the
21 given to devfreq.
23 When OPP is used with the devfreq device, it is recommended to
24 register devfreq's nb to the OPP's notifier head. If OPP is
25 used with the devfreq device, you may use OPP helper
26 functions defined in devfreq.h.
