Hi Tingwei,
Apologies for the untimely response to this set, I am hoping to get to it in the next two weeks.
It's fine, Mathieu. Please let me know your comments once you have time. I'm targeting to get these set merged in 5.10 Kernel.
Thanks, Mathieu

Allow to build coresight as modules. This gives developers the
feasibility to
test their code without reboot.
This series is based on below two series.
- "coresight: allow to build components as modules" https://lkml.org/lkml/2018/6/5/989
- "coresight: make drivers modular" https://lkml.org/lkml/2020/1/17/468
Change from v8: Protect etmdrvdata[] by modifying it on relevant CPU (Mathieu and
Suzuki)
Grab the device before allocating memory for the node (Mathieu) Add author of coresight core driver (Mathieu)
Change from v7: Depends on below change for ETM hotplug (Sai)
https://lore.kernel.org/linux-arm-kernel/20200729051310.18436-1-saiprakash .ranjan@codeaurora.org/
Add mutex lock to protect etmdrvdata[] (Suzuki) Add helper function coresight_get_ref() (Suzuki) Reorg replicator and funnel change. Use two patches to support these two drivers. (Suzuki) Add fix tag to "coresight: etm: perf: Fix warning caused by
etm_setup_aux
failure" (Suzuki) Update author of "coresight: cti: Fix bug clearing sysfs links on
callback"
Change from v6: Correct module description for CATU (Mike) Check ect_ret equals 0 and set ect_enabled flag (Mike) Add Tested-by and Reviewed-by from Mike
Change from v5: Add below CTI clean up change from Mike into series -https://lists.linaro.org/pipermail/coresight/2020-July/004349.html Increase module reference count when enabling CTI device (Mike)
Change from v4: Fix error handling in coresight_grab_devicei() (Greg) Add coresight: cti: Fix remove sysfs link error from Mike -https://lists.linaro.org/pipermail/coresight/2020-July/004275.html Move cti_remove_conn_xrefs() into cti_remove() (Mike) Align patch subject to coresight: <component>: <description> (Mike)
Change from v3: Rebase to coresight-next (Mike and Mathieu) Reorder try_get_module() (Suzuki) Clean up etmdrvdata[] in device remote path (Mike) Move cti_remove_conn_xrefs to cti_remove (Mike)
Change from v2: Rebase to 5.8-rc5. Export coresight_add_sysfs_link and coresight_remove_sysfs_link Fix one cut and paste error on MODULE_DESCRIPTION of CTI
Change from v1: Use try_module_get() to avoid module to be unloaded when device is used in active trace session. (Mathieu P)
Change from above two series. This series adds the support to dynamically remove module when the
device in
that module is enabled and used by some trace path. It disables all
trace
paths with that device and release the trace path.
