4 bool "Enable U-Boot watchdog reset"
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.
14 config WATCHDOG_RESET_DISABLE
15 bool "Disable reset watchdog"
17 Disable reset watchdog, which can let WATCHDOG_RESET invalid, so
18 that the watchdog will not be fed in u-boot.
21 bool "Enable BCM2835/2836 watchdog driver"
24 Say Y here to enable the BCM2835/2836 watchdog
26 This provides basic infrastructure to support BCM2835/2836 watchdog
27 hardware, with a max timeout of ~15secs.
30 bool "TI OMAP watchdog driver"
31 depends on ARCH_OMAP2PLUS
35 Say Y here to enable the OMAP3+ watchdog driver.
37 config TANGIER_WATCHDOG
38 bool "Intel Tangier watchdog"
42 This enables support for watchdog controller available on
43 Intel Tangier SoC. If you're using a board with Intel Tangier
47 bool "i.MX7ULP watchdog"
49 Say Y here to enable i.MX7ULP watchdog driver.
52 bool "Enable driver model for watchdog timer drivers"
56 Enable driver model for watchdog timer. At the moment the API
57 is very simple and only supports four operations:
58 start, stop, reset and expire_now (expire immediately).
59 What exactly happens when the timer expires is up to a particular
63 bool "Enable Watchdog Timer support for Sandbox"
64 depends on SANDBOX && WDT
66 Enable Watchdog Timer support in Sandbox. This is a dummy device that
67 can be probed and supports all of the methods of WDT, but does not

71 bool "Marvell Armada 37xx watchdog timer support"
72 depends on WDT && ARMADA_3700
74 Enable this to support Watchdog Timer on Marvell Armada 37xx SoC.
75 There are 4 possible clocks which can be used on these SoCs. This
76 driver uses the second clock (ID 1), assuming that so will also

82 default y if ARCH_ASPEED
84 Select this to enable watchdog timer for Aspeed ast2500/ast2400 devices.
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
91 bool "BCM6345 watchdog timer support"
92 depends on WDT && (ARCH_BMIPS || ARCH_BCM6858 || ARCH_BCM63158)
94 Select this to enable watchdog timer for BCM6345 SoCs.
95 The watchdog timer is stopped when initialized.
96 It performs full SoC reset.
