The packets16 that the Network on Chip (NoC) probes detects are transported over the17 network infrastructure to observer units. You can configure probes to capture18 packets with header or data on the data request response network, or as19 traffic debug or statistic collectors. Exynos542x bus has multiple NoC probes20 to provide bandwidth information about behavior of the SoC that you can use21 while analyzing system performance.22 23properties:24 compatible:25 const: samsung,exynos5420-nocp26 27 clock-names:28 items:29 - const: nocp30 31 clocks:32 maxItems: 133 34 reg:35 maxItems: 136 37required:38 - compatible39 - reg40 41additionalProperties: false42 43examples:44 - |45 nocp_mem0_0: nocp@10ca1000 {46 compatible = "samsung,exynos5420-nocp";47 reg = <0x10ca1000 0x200>;48 };49
