3config WATCHDOG
4	bool "Enable U-Boot watchdog reset"
5	help
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.

52	bool "Enable driver model for watchdog timer drivers"
53	depends on DM
54	help
55	  Enable driver model for watchdog timer. At the moment the API
56	  is very simple and only supports four operations:
57	  start, restart, stop and reset (expire immediately).
58	  What exactly happens when the timer expires is up to a particular
59	  device/driver.
