98c2ecf20Sopenharmony_ci * The PTI (Parallel Trace Interface) driver directs trace data routed from
108c2ecf20Sopenharmony_ci * various parts in the system out through the Intel Penwell PTI port and
118c2ecf20Sopenharmony_ci * out of the mobile device for analysis with a debugging tool
128c2ecf20Sopenharmony_ci * (Lauterbach, Fido). This is part of a solution for the MIPI P1149.7,
138c2ecf20Sopenharmony_ci * compact JTAG, standard.
