  19  * The PTI (Parallel Trace Interface) driver directs trace data routed from
  20  * various parts in the system out through the Intel Penwell PTI port and
  21  * out of the mobile device for analysis with a debugging tool
  22  * (Lauterbach, Fido). This is part of a solution for the MIPI P1149.7,
  23  * compact JTAG, standard.
  24  *
  25  * This header file is used by n_tracerouter to be able to send the
  26  * data of it's tty port to the tty port this module sits.  This
  27  * mechanism can also be used independent of the PTI module.
