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

54 Enable driver model for watchdog timer. At the moment the API
55 is very simple and only supports four operations:
Patrice Chotard0a060242019-04-25 12:57:28 +020056 start, stop, reset and expire_now (expire immediately).
maxims@google.comdaea6d42017-04-17 12:00:21 -070057 What exactly happens when the timer expires is up to a particular
58 device/driver.
