^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) This framework provides a standard kernel interface for Dynamic Voltage and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) Frequency Switching on arbitrary devices.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) It exposes controls for adjusting frequency through sysfs files which are
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) similar to the cpufreq subsystem.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) Devices for which current usage can be measured can have their frequency
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) automatically adjusted by governors.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) Device drivers need to initialize a :c:type:`devfreq_profile` and call the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) :c:func:`devfreq_add_device` function to create a :c:type:`devfreq` instance.
