2 | * Samsung Exynos NoC (Network on Chip) Probe device | |
3 | ||
4 | The Samsung Exynos542x SoC has NoC (Network on Chip) Probe for NoC bus. | |
5 | NoC provides the primitive values to get the performance data. The packets | |
6 | that the Network on Chip (NoC) probes detects are transported over | |
7 | the network infrastructure to observer units. You can configure probes to | |
8 | capture packets with header or data on the data request response network, | |
9 | or as traffic debug or statistic collectors. Exynos542x bus has multiple | |
10 | NoC probes to provide bandwidth information about behavior of the SoC | |
11 | that you can use while analyzing system performance. | |
12 | ||
13 | Required properties: | |
14 | - compatible: Should be "samsung,exynos5420-nocp" | |
15 | - reg: physical base address of each NoC Probe and length of memory mapped region. | |
16 | ||
17 | Optional properties: | |
18 | - clock-names : the name of clock used by the NoC Probe, "nocp" | |
19 | - clocks : phandles for clock specified in "clock-names" property | |
20 | ||
21 | Example : NoC Probe nodes in Device Tree are listed below. | |
