Hello,
Did anyone do some work on a driver to use the GPIO pins on the VIA Epia
boards based around the vt8237 or CX700?
E.g. my Epia LT offers 8 programamble GPIO pins according to the
documentation (see below for layout) but I'd like to know if there is a
driver so I can actually use them and e.g. receive an interrupt when a
GPIO goes high or low.
Please let us know what is available.
Thanks,
Udo
