Quick correction - you need to look for enable_source / enable_sink

Hi
As this is a sysfs only update - would it not be easier to simply use
a shell script to iterate through coresight/devices/ looking for
disable_source / disable_sink files and setting those accordingly?
See tools/perf/tests/shell/test_arm_coresight.sh for an example of a
script that does similar iteration to test coresight in perf

Hi Mike & Suzuki,
Sometimes user just want to have some quick test from PC with adb commands.
It is very easy to reset all sources and sinks' status by command below.
echo 1 > /sys/bus/coresight/reset_source_sink
Preparing the script for test is not easy for users who are not familiar
with the coresight framework.
Thanks
