Different revision of i.MX8MN EVK boards may have different external pull up registor design, some are enabled while some are NOT, to make sure the WDOG_B pin works properly, better to enable internal pull up resistor. Since enabling internal pull up resistor is NOT harmful and having benefit of flexibility on different board design, just enable it for all i.MX8MN boards; And schmitt input is NOT necessary for this WDOG_B output pin, so remove it; Open drain outputs provide more flexibility to a designer as they can be pulled-up to any voltage found in the system, so enable it as well.
