Different revision of i.MX8MM 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.MX8MM boards.
