    description:
      Add this property to disable the watchdog during suspend.
      Only use this option if you can't use the watchdog automatic suspend
      function during a suspend (see register CONTROL_B).

    enum: [0, 1]
    description:
      Set what happens on watchdog timeout. If this bit is set the
      watchdog timeout triggers SHUTDOWN, if cleared the watchdog triggers
      POWERDOWN. Can be 0 or 1. Only use this option if you want to change the
      default chip's OTP setting for WATCHDOG_SD bit. If this property is NOT
      set the WATCHDOG_SD bit and on timeout watchdog behavior will match the
      chip's OTP settings.
