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

40	depends on SANDBOX && WDT
41	help
42		Enable Watchdog Timer support in Sandbox. This is a dummy device that
43		can be probed and supports all of the methods of WDT, but does not
44		really do anything.

50	help
51	  Select this to enable watchdog timer for Aspeed ast2500/ast2400 devices.
52	  The watchdog timer is stopped when initialized. It performs reset, either
53	  full SoC reset or CPU or just some peripherals, based on the flags.
54	  It currently does not support Boot Flash Addressing Mode Detection or
55	  Second Boot.
