Is enable_{source,sink} integer-valued or bit (0/1)? In other words, is
it OK to `echo 2` to both sysfs files?

For consistency, inline this sysfs also (thus
``/sys/bus/coresight/devices``.

IMO I prefer `PS1=\$` (that is, omit the directory). Alternatively,
you can write `ls -l /sys/bus/coresight/devices | grep dummy` (specify
the directory to `ls`).
