 * The PTI (Parallel Trace Interface) driver directs trace data routed from
 * various parts in the system out through the Intel Penwell PTI port and
 * out of the mobile device for analysis with a debugging tool
 * (Lauterbach, Fido). This is part of a solution for the MIPI P1149.7,
 * compact JTAG, standard.

 * This header file is used by n_tracerouter to be able to send the
 * data of it's tty port to the tty port this module sits.  This
 * mechanism can also be used independent of the PTI module.
