* 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.
