1 2* Rockchip NoC (Network on Chip) Probe device 3 4The Rockchip SoCs have NoC (Network on Chip) Probe for NoC bus. 5NoC provides the primitive values to get the performance data, The 6packets that the Network on Chip (NoC) probes detects are transported 7over the network infrastructure to observer units. For example, RK3399 8has multiple NoC probes to monitor traffic statistics for analyzing the 9transaction flow. 10 11Required properties: 12- compatible: Should be one of the following. 13 - "rockchip,rk3288-nocp" - for RK3288 SoC. 14 - "rockchip,rk3368-nocp" - for RK3368 SoC. 15 - "rockchip,rk3399-nocp" - for RK3399 SoC. 16 - "rockchip,rk3568-nocp" - for RK3568 SoC. 17- reg: physical base address of each NoC Probe and length of memory mapped region. 18 19Example : NoC Probe nodes in Device Tree are listed below. 20 21 nocp_cci_msch0: nocp-cci-msch0@ffa86000 { 22 compatible = "rockchip,rk3399-nocp"; 23 reg = <0xffa86000 0x400>; 24 }; 25
