Without the patch: If the system boot with watchdog enabled (by the bootloader), the driver sets up a threads to pet the watchdog. With the patch, imx2_wdt_ping() is called once during probe but the thread is not started. There are no timeout or early_timeout paremters in the DT or in the kernel command line. I don't like the old behaviour, but I think there are some setups that rely on this feature.
