Could you use the the same way that Linux handles the imx2_wdt?

Please see the commit below:

    watchdog: imx: Add DT ext-reset handling

    The Linux imx2_wdt driver uses a fsl,ext-reset-output boolean in the
    device tree to specify whether the board design should use the external
    reset instead of the internal reset. Use this boolean to determine which
    mode to use rather than using external reset unconditionally.

    For the legacy non-DM mode, the external reset is always used in order
    to maintain the previous behavior.
