539f40346SAlexander Shishkin	  Intel(R) Trace Hub (TH) is a set of hardware blocks (subdevices) that
639f40346SAlexander Shishkin	  produce, switch and output trace data from multiple hardware and
739f40346SAlexander Shishkin	  software sources over several types of trace output ports encoded
839f40346SAlexander Shishkin	  in System Trace Protocol (MIPI STPv2) and is intended to perform
939f40346SAlexander Shishkin	  full system debugging.
