| * 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>; |
| }; |
