| 4 | The devfreq-event device provide the raw data and events which |
| 5 | indicate the current state of devfreq-event device. The provided |
| 6 | data from devfreq-event device is used to monitor the state of |
| 7 | device and determine the suitable size of resource to reduce the |
| 8 | wasted resource. |

| 10 | The devfreq-event device can support the various type of events |
| 11 | (e.g., raw data, utilization, latency, bandwidth). The events |
| 12 | may be used by devfreq governor and other subsystem. |
