 6	  A System Trace Module (STM) is a device exporting data in System
 7	  Trace Protocol (STP) format as defined by MIPI STP standards.
 8	  Examples of such devices are Intel(R) Trace Hub and Coresight STM.

17	  This is a simple dummy device that pretends to be an stm device
18	  and discards your data. Use for stm class testing.

25	  This is a kernel space trace source that sends kernel log

33	help
34	  This is a kernel space trace source that sends periodic
35	  heartbeat messages to trace hosts over STM devices. It is
36	  also useful for testing stm class drivers and the stm class
37	  framework itself.

45	help
46	  This option can be used to copy the output from kernel Ftrace
47	  to STM engine. Enabling this option will introduce a slight
48	  timing effect.
