1*4882a593Smuzhiyun 2*4882a593Smuzhiyun* Rockchip NoC (Network on Chip) Probe device 3*4882a593Smuzhiyun 4*4882a593SmuzhiyunThe Rockchip SoCs have NoC (Network on Chip) Probe for NoC bus. 5*4882a593SmuzhiyunNoC provides the primitive values to get the performance data, The 6*4882a593Smuzhiyunpackets that the Network on Chip (NoC) probes detects are transported 7*4882a593Smuzhiyunover the network infrastructure to observer units. For example, RK3399 8*4882a593Smuzhiyunhas multiple NoC probes to monitor traffic statistics for analyzing the 9*4882a593Smuzhiyuntransaction flow. 10*4882a593Smuzhiyun 11*4882a593SmuzhiyunRequired properties: 12*4882a593Smuzhiyun- compatible: Should be one of the following. 13*4882a593Smuzhiyun - "rockchip,rk3288-nocp" - for RK3288 SoC. 14*4882a593Smuzhiyun - "rockchip,rk3368-nocp" - for RK3368 SoC. 15*4882a593Smuzhiyun - "rockchip,rk3399-nocp" - for RK3399 SoC. 16*4882a593Smuzhiyun - "rockchip,rk3568-nocp" - for RK3568 SoC. 17*4882a593Smuzhiyun- reg: physical base address of each NoC Probe and length of memory mapped region. 18*4882a593Smuzhiyun 19*4882a593SmuzhiyunExample : NoC Probe nodes in Device Tree are listed below. 20*4882a593Smuzhiyun 21*4882a593Smuzhiyun nocp_cci_msch0: nocp-cci-msch0@ffa86000 { 22*4882a593Smuzhiyun compatible = "rockchip,rk3399-nocp"; 23*4882a593Smuzhiyun reg = <0xffa86000 0x400>; 24*4882a593Smuzhiyun }; 25
