  9. * The PTI (Parallel Trace Interface) driver directs trace data routed from
  10. * various parts in the system out through the Intel Penwell PTI port and
  11. * out of the mobile device for analysis with a debugging tool
  12. * (Lauterbach, Fido). This is part of a solution for the MIPI P1149.7,
  13. * compact JTAG, standard.
  14. *
  15. * This header file is used by n_tracerouter to be able to send the
  16. * data of it's tty port to the tty port this module sits. This
  17. * mechanism can also be used independent of the PTI module.
