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.

56 Enable driver model for watchdog timer. At the moment the API
57 is very simple and only supports four operations:
Patrice Chotard0a060242019-04-25 12:57:28 +020058 start, stop, reset and expire_now (expire immediately).
maxims@google.comdaea6d42017-04-17 12:00:21 -070059 What exactly happens when the timer expires is up to a particular
60 device/driver.

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