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. + +properties: + compatible: + const: samsung,exynos5420-nocp + + clock-names: + items: + - const: nocp + + clocks: + maxItems: 1 + + reg: + maxItems: 1 + +required: + - compatible + - reg + +additionalProperties: false + +examples: + - | + nocp_mem0_0: nocp@10ca1000 { + compatible = "samsung,exynos5420-nocp"; + reg = <0x10ca1000 0x200>; + }; -- cgit v1.2.3
