10	  Say Y here to enable the BCM2835/2836 watchdog
11
12	  This provides basic infrastructure to support BCM2835/2836 watchdog
13	  hardware, with a max timeout of ~15secs.

23config TANGIER_WATCHDOG
24	bool "Intel Tangier watchdog"
25	depends on INTEL_MID
26	select HW_WATCHDOG
27	help
28	  This enables support for watchdog controller available on
29	  Intel Tangier SoC. If you're using a board with Intel Tangier
30	  SoC, say Y here.

32config ULP_WATCHDOG
33	bool "i.MX7ULP watchdog"
34	help
35	  Say Y here to enable i.MX7ULP watchdog driver.

37config WDT
38	bool "Enable driver model for watchdog timer drivers"
39	depends on DM
40	help
41	  Enable driver model for watchdog timer. At the moment the API
42	  is very simple and only supports four operations:
43	  start, restart, stop and reset (expire immediately).
44	  What exactly happens when the timer expires is up to a particular
45	  device/driver.
46
47config WDT_SANDBOX
48	bool "Enable Watchdog Timer support for Sandbox"
49	depends on SANDBOX && WDT
50	help
51		Enable Watchdog Timer support in Sandbox. This is a dummy device that
52		can be probed and supports all of the methods of WDT, but does not
53		really do anything.

55config WDT_ASPEED
56	bool "Aspeed ast2400/ast2500 watchdog timer support"
57	depends on WDT
58	default y if ARCH_ASPEED
59	help
60	  Select this to enable watchdog timer for Aspeed ast2500/ast2400 devices.
61	  The watchdog timer is stopped when initialized. It performs reset, either
62	  full SoC reset or CPU or just some peripherals, based on the flags.
63	  It currently does not support Boot Flash Addressing Mode Detection or
64	  Second Boot.

66config WDT_BCM6345
67	bool "BCM6345 watchdog timer support"
68	depends on WDT && ARCH_BMIPS
69	help
70	  Select this to enable watchdog timer for BCM6345 SoCs.
71	  The watchdog timer is stopped when initialized.
72	  It performs full SoC reset.

74config WDT_ORION
75	bool "Orion watchdog timer support"
76	depends on WDT
77	help
78	   Select this to enable Orion watchdog timer, which can be found on some
79	   Marvell Armada chips.
