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 PM_DEVFREQ_EVENT config DEVFREQ_EVENT_EXYNOS_NOCP tristate "Exynos NoC (Network On Chip) Probe DEVFREQ event Driver" depends on ARCH_EXYNOS || COMPILE_TEST select PM_OPP select REGMAP_MMIO help This add the devfreq-event driver for Exynos SoC.
