+Optional properties:
+- timeout-sec : Timeout of the watchdog in seconds
+ If this timeout is not defined, the value of WATCHDOG_TIMEOUT_MSECS will
+ be used instead.
+- hw_margin_ms : Period used to reset the watchdog in ms
+ If this period is not defined, the default value is 1000.
+- u-boot,noautostart : Specify that this watchdog should not autostart
+ When the config option WATCHDOG_AUTOSTART is set, all enabled
+ watchdogs are started. This property allows specifying that this
+ watchdog should NOT be started.
