+          The devfreq-event device provide the raw data and events which
+          indicate the current state of devfreq-event device. The provided
+          data from devfreq-event device is used to monitor the state of
+          device and determine the suitable size of resource to reduce the
+          wasted resource.
+
+          The devfreq-event device can support the various type of events
+          (e.g., raw data, utilization, latency, bandwidth). The events
+          may be used by devfreq governor and other subsystem.
