These trace components can generally be classified as19 sinks, links and sources. Trace data produced by one or more sources flows20 through the intermediate links connecting the source to the currently selected21 sink.22 23 The Coresight replicator splits a single trace stream into two trace streams24 for systems that have more than one trace sink component.25 26properties:27 compatible:28 const: arm,coresight-static-replicator29 30 power-domains:31 maxItems: 132 33 in-ports:34 $ref: /schemas/graph.yaml#/properties/ports35 additionalProperties: false36 37 properties:38 port:39 description: Input connection from CoreSight Trace bus40 $ref: /schemas/graph.yaml#/properties/port41 42 out-ports:43 $ref: /schemas/graph.yaml#/properties/ports44 45 patternProperties:46 '^port@[01]$':47 description: Output connections to CoreSight Trace bus48 $ref: /schemas/graph.yaml#/properties/port49 50required:51 - compatible52 - in-ports53 - out-ports54 55additionalProperties: false56 57examples:58 - |59 replicator {60 /*61 * non-configurable replicators don't show up on the62 * AMBA bus.
