I guessed so from the quick glance at it as it needs descriptors with
notion of source, sink and links to register. However I felt odd to not
group under the same "coresight" bus. As someone with least knowledge
on coresight, I would check under "sys/bus/coresight" to check available
devices on the system.

Anyways that's just my thoughts though I agree with you. It may need
more refactoring to support that and it will look hackish if we try to
do that with the code as it stands.
