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. | |
