5	  The devfreq-event device provide the raw data and events which
6	  indicate the current state of devfreq-event device. The provided
7	  data from devfreq-event device is used to monitor the state of
8	  device and determine the suitable size of resource to reduce the
9	  wasted resource.

11	  The devfreq-event device can support the various type of events
12	  (e.g., raw data, utilization, latency, bandwidth). The events
13	  may be used by devfreq governor and other subsystem.
