| 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. |
