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 NoC
(Network on Chip) Probe counters to measure the bandwidth of AXI bus.

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