Rather than have your current approach of dev nodes + sysfs config files for each coresight device, I think it might be better to follow something closer to ftrace and stick per-device directories under debugfs/coresight/. Then you can have a pipe file and some config files in the same directory for each component. You also don't need to do any mapping operations with this (just post-process the stream directly). It might also be fun to play with file redirection for sources and sinks, but that's probably a bit too invasive.
