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.
