| 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. | |
