Subject: [PATCH 0/3] coresight-tnoc: Add support for Interconnect TNOC

This patch series adds support for the Qualcomm CoreSight Interconnect TNOC
(Trace Network On Chip) block, which acts as a CoreSight graph link forwarding
trace data from subsystems to the Aggregator TNOC. Unlike the Aggregator TNOC,
this block does not support aggregation or ATID assignment.
