1* Samsung Exynos NoC (Network on Chip) Probe device23The Samsung Exynos542x SoC has NoC (Network on Chip) Probe for NoC bus.4NoC provides the primitive values to get the performance data. The packets5that the Network on Chip (NoC) probes detects are transported over6the network infrastructure to observer units. You can configure probes to7capture packets with header or data on the data request response network,8or as traffic debug or statistic collectors. Exynos542x bus has multiple9NoC probes to provide bandwidth information about behavior of the SoC10that you can use while analyzing system performance.1112Required properties:13- compatible: Should be "samsung,exynos5420-nocp"14- reg: physical base address of each NoC Probe and length of memory mapped region.1516Optional properties:17- clock-names : the name of clock used by the NoC Probe, "nocp"18- clocks : phandles for clock specified in "clock-names" property1920Example : NoC Probe nodes in Device Tree are listed below.2122nocp_mem0_0: nocp@10ca1000 {23compatible = "samsung,exynos5420-nocp";24reg = <0x10CA1000 0x200>;25};262728
