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

53 Enable driver model for watchdog timer. At the moment the API
54 is very simple and only supports four operations:
Patrice Chotard8d4f91b2019-04-25 12:57:28 +0200[diff] [blame]55 start, stop, reset and expire_now (expire immediately).
maxims@google.com0753bc22017-04-17 12:00:21 -0700[diff] [blame]56 What exactly happens when the timer expires is up to a particular
