I can't find my old post, so I apologize for any repeat post.
I am trying to allocate two pins (P8_12,P8_46) to PRU0 and PRU1. So
effectively mode 6 and mode 5. I want to exclusively use these by the
pru(s). Still trying to understand this device tree overlay, but I found
an example one and modified it. It gives a syntax error when ti toy to
compile it (dtc). After beating my head against the wall, I am hoping a
second set of eyes will be helpful. Any help one can give on the syntax
error (and if the dts file won't accomplish what the desire for these pins).

Again, thanks ahead for any hep one can offer!
