[GIT PULL] coresight: Updates for v6.3

[Suzuki K Poulose]

Hi Greg,

Please find the updates for CoreSight and hwtracing subsystem for inclusion
in v6.3. fyi, there is a patch to export perf_report_aux_output_id(), a perf
generic helper for emitting AUX packet. 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.

Suzuki

----------------------------------------------------------------
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
