This patch adds NoC (Network on Chip) Probe driver which provides the primitive values to get the performance data. The packets that the Network on Chip (NoC) probes detects are transported over the network infrastructure. Exynos542x bus has multiple NoC probes to provide bandwidth information about behavior of the SoC that you can use while analyzing system performance.

(e.g., raw data, utilization, latency, bandwidth). The events
|
|
may be used by devfreq governor and other subsystem.
