This has been Acked by Peter and is used by the CoreSight dynamic trace id allocation scheme. Hence routing via the coresight tree. Kindly consider pulling.

(2023-01-30 11:45:32 +0000) ---------------------------------------------------------------- coresight: Updates for v6.3 - Dynamic TraceID allocation scheme for CoreSight trace source. Allows systems with > 44 CPUs to use the ETMs. TraceID is advertised via AUX_OUTPUT_HWID packets in perf.data. Also allows allocating trace-ids for non-CPU bound trace components (e.g., Qualcomm TPDA). - Support for Qualcomm TPDA and TPDM CoreSight devices. - Support for Ultrasoc SMB CoreSight Sink buffer. - Fixes for HiSilicon PTT driver - MAINTAINERS update: Add Reviewer for HiSilicon PTT driver - Bug fixes for CTI power management and sysfs mode - Fix CoreSight ETM4x TRCSEQRSTEVRn access Signed-off-by: Suzuki K Poulose ---------------------------------------------------------------- Arnd Bergmann (1): Coresight: tpda/tpdm: remove incorrect __exit annotation Bagas Sanjaya (2): Documentation: coresight: Extend title heading syntax in TPDM and TPDA documentation Documentation: coresight: tpdm: Add dummy comment after sysfs list James Clark (2): coresight: cti: Prevent negative values of enable count coresight: cti: Remove atomic type from enable_req_count Junhao He (1): coresight: etm4x: Fix accesses to TRCSEQRSTEVR and TRCSEQSTR Mao Jinlong (9): coresight: cti: Add PM runtime call in enable_store coresight: core: Use IDR for non-cpu bound sources' paths.
