What: /sys/bus/coresight/devices/<memory_map>.etm/enable_source
Date: April 2015
KernelVersion: 4.01
Contact: Mathieu Poirier <mathieu.poirier@linaro.org>
Description: (RW) Enable/disable tracing on this specific trace entiry.
Enabling a source implies the source has been configured
properly and a sink has been identidifed for it. The path
of coresight components linking the source to the sink is
configured and managed automatically by the coresight framework.
