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. if [31mCONFIG_PM_DEVFREQ_EVENT[0m config [31mCONFIG_DEVFREQ_EVENT_EXYNOS_NOCP[0m tristate "EXYNOS NoC (Network On Chip) Probe DEVFREQ event Driver" depends on [31mCONFIG_ARCH_EXYNOS[0m || [31mCONFIG_COMPILE_TEST[0m select [31mCONFIG_PM_OPP[0m select [31mCONFIG_REGMAP_MMIO[0m help This add the devfreq-event driver for Exynos SoC.
