+       help
+         This option enables U-Boot watchdog support where U-Boot is using
+         watchdog_reset function to service watchdog device in U-Boot. Enable
+         this option if you want to service enabled watchdog by U-Boot. Disable
+         this option if you want U-Boot to start watchdog but never service it.

+
+         This provides basic infrastructure to support BCM2835/2836 watchdog
+         hardware, with a max timeout of ~15secs.

+       depends on DM
+       help
+         Enable driver model for watchdog timer. At the moment the API
+         is very simple and only supports four operations:
+         start, restart, stop and reset (expire immediately).
+         What exactly happens when the timer expires is up to a particular
+         device/driver.

+               Enable Watchdog Timer support in Sandbox. This is a dummy device that
+               can be probed and supports all of the methods of WDT, but does not
+               really do anything.

+         The watchdog timer is stopped when initialized. It performs reset, either
+         full SoC reset or CPU or just some peripherals, based on the flags.
+         It currently does not support Boot Flash Addressing Mode Detection or
+         Second Boot.
