If that makes you feel any better, I was not planning on going further
than that, and yes, removing this driver and using gpio_wdt.c would be
the way to go, this driver greatly predates gpio_wdt.c and I have since
then not had access to my MTX-1 platforms which is why this did not
happen. We can attempt a "blind conversion" without testing, but what
good would that make, not sure.
