Changes since v2:
- Drop the patches exposing device links via sysfs, to be posted as separate
series.

Thanks for sharing the git tree linkage in another email. Just want
to confirm, since patch set v3 you have dropped the patch "coresight:
Expose device connections via sysfs" [1], will you send out this patch
after ACPI binding support patches has been merged?

We are awaiting Mike's comment on the approach, as his CTI support also
needs something similar.


When you send out the new patch for exposing device connection, please
loop me so that I can base on it for perf testing related works.

Sure, will do. As such, the perf testing should not be affected by that
series. It is just a helper to demonstrate the connections. But yes, it
will definitely help you to choose an ETF for a cluster, if you had multiple
ETFs on the system. Otherwise, you should be OK.

Please be aware that the power management support is missing on ACPI platform.
So you must make sure, by other means, that the debug domain is powered up.
