The WDOG_ANY signal is connected to the RESET_IN signal of the SoM and baseboard. It is currently configured as push-pull, which means that if some external device like a programmer wants to assert the RESET_IN signal by pulling it to ground, it drives against the high level WDOG_ANY output of the SoC. To fix this we set the WDOG_ANY signal to open-drain configuration. That way we make sure that the RESET_IN can be asserted by the watchdog as well as by external devices.
