These trace components can generally be classified as 19 sinks, links and sources. Trace data produced by one or more sources flows 20 through the intermediate links connecting the source to the currently selected 21 sink. 22 23 The Coresight replicator splits a single trace stream into two trace streams 24 for systems that have more than one trace sink component. 25 26properties: 27 compatible: 28 const: arm,coresight-static-replicator 29 30 power-domains: 31 maxItems: 1 32 33 in-ports: 34 $ref: /schemas/graph.yaml#/properties/ports 35 additionalProperties: false 36 37 properties: 38 port: 39 description: Input connection from CoreSight Trace bus 40 $ref: /schemas/graph.yaml#/properties/port 41 42 out-ports: 43 $ref: /schemas/graph.yaml#/properties/ports 44 45 patternProperties: 46 '^port@[01]$': 47 description: Output connections to CoreSight Trace bus 48 $ref: /schemas/graph.yaml#/properties/port 49 50required: 51 - compatible 52 - in-ports 53 - out-ports 54 55additionalProperties: false 56 57examples: 58 - | 59 replicator { 60 /* 61 * non-configurable replicators don't show up on the 62 * AMBA bus.
