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 static funnel merges 2-8 trace sources into a single trace24 stream.25 26properties:27 compatible:28 const: arm,coresight-static-funnel29 30 power-domains:31 maxItems: 132 33 in-ports:34 $ref: /schemas/graph.yaml#/properties/ports35 36 patternProperties:37 '^port@[0-7]$':38 description: Input connections from CoreSight Trace bus39 $ref: /schemas/graph.yaml#/properties/port40 41 out-ports:42 $ref: /schemas/graph.yaml#/properties/ports43 additionalProperties: false44 45 properties:46 port:47 description: Output connection to CoreSight Trace bus48 $ref: /schemas/graph.yaml#/properties/port49 50required:51 - compatible52 - in-ports53 - out-ports54 55additionalProperties: false56 57examples:58 - |59 funnel {60 /*61 * non-configurable replicators don't show up on the62 * AMBA bus.
