This patch allows n_tracerouter and n_tracesink to be compiled and
configured in the Linux kernel.

+          The trace router uses the Linux tty line discipline framework to
+          route trace data coming from a tty port (say UART for example) to
+           the trace sink line discipline driver and to another tty port(say USB).
+           This is part of a solution for the MIPI P1149.7, compact JTAG,
+           standard, which is for debugging mobile devices. The PTI driver in
+           drivers/misc/pti.c defines the majority of this MIPI solution.
+
+          You should select this driver if the target kernel is meant for
+          a mobile device containing a modem.  Then you will need to select
+          "Trace data sink for MIPI P1149.7 cJTAG standard" line discipline
+          driver.

+        ---help---
+          The trace sink uses the Linux line discipline framework to receive
+          trace data coming from the trace router line discipline driver
+          to a user-defined tty port target, like USB.
+          This is to provide a way to extract modem trace data on
+          devices that do not have a PTI HW module, or just need modem
+          trace data to come out of a different HW output port.
+          This is part of a solution for the P1149.7, compact JTAG, standard.

+          If you select this option, you need to select
+          "Trace data router for MIPI P1149.7 cJTAG standard".
