| * Samsung Exynos NoC (Network on Chip) Probe device | |
| The Samsung Exynos542x SoC has NoC (Network on Chip) Probe for NoC bus. | |
| NoC 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 to observer units. You can configure probes to | |
| capture packets with header or data on the data request response network, | |
| or as traffic debug or statistic collectors. Exynos542x bus has multiple | |
| NoC probes to provide bandwidth information about behavior of the SoC | |
| that you can use while analyzing system performance. | |
| Required properties: | |
| - compatible: Should be "samsung,exynos5420-nocp" | |
| - reg: physical base address of each NoC Probe and length of memory mapped region. | |
| Optional properties: | |
| - clock-names : the name of clock used by the NoC Probe, "nocp" | |
| - clocks : phandles for clock specified in "clock-names" property | |
| Example : NoC Probe nodes in Device Tree are listed below. | |
| nocp_mem0_0: nocp@10ca1000 { | |
| compatible = "samsung,exynos5420-nocp"; | |
| reg = <0x10CA1000 0x200>; | |
| }; |
