It was marked compatible with "qcom,coresight-itnoc", an Interconnect TNOC, which is never assigned an ATID. As a result the aggregator had no trace ID and could not tag the merged trace. An Interconnect TNOC is a subsystem-level aggregator: it merges trace from the ATB sources within its subsystem (TPDMs and other ATB masters) and forwards the combined stream to the system-level Aggregator TNOC. It carries no ATID of its own, because the Aggregator TNOC downstream in the path already owns the ATID. Switch the node to "qcom,coresight-tnoc" so it is described as the Aggregator TNOC it is and is assigned a system trace ID. Rename the node to "tn" and use the "apb_pclk" clock name as required by the Aggregator TNOC binding.
