Also, the clocks are not enabled in probe (pm_runtime_enable() doesn't do that), thus this is another indicator that the watchdog wasn't used previously like this. Instead, keep the watchdog hardware in its previous state at probe (by default it is in reset state), enable it when it is started and move it to reset state when it is stopped. This saves some extra power when the watchdog is unused.
