menuconfig PM_DEVFREQ_EVENT
	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.

	help
	  This add the devfreq-event driver for Exynos SoC. It provides PPMU
	  (Platform Performance Monitoring Unit) counters to estimate the
	  utilization of each module.

	depends on ARCH_ROCKCHIP
	help
	  This add the devfreq-event driver for Rockchip SoC. It provides DFI
	  (DDR Monitor Module) driver to count ddr load.
