+ bool "DEVFREQ-Event device Support"
+ help
+ 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.
