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 "Enable Watchdog Timer support for IMX and LSCH2 of NXP"
31 select HW_WATCHDOG if !WDT
33 Select this to enable the IMX and LSCH2 of Layerscape watchdog
37 bool "TI OMAP watchdog driver"

42 Say Y here to enable the OMAP3+ watchdog driver.
45 bool "i.MX7ULP watchdog"
47 Say Y here to enable i.MX7ULP watchdog driver.
50 bool "Enable driver model for watchdog timer drivers"
54 Enable driver model for watchdog timer. At the moment the API
55 is very simple and only supports four operations:
56 start, stop, reset and expire_now (expire immediately).
57 What exactly happens when the timer expires is up to a particular

61 bool "Marvell Armada 37xx watchdog timer support"
62 depends on WDT && ARMADA_3700
64 Enable this to support Watchdog Timer on Marvell Armada 37xx SoC.
65 There are 4 possible clocks which can be used on these SoCs. This
66 driver uses the second clock (ID 1), assuming that so will also
70 bool "Aspeed ast2400/ast2500 watchdog timer support"
72 default y if ARCH_ASPEED
74 Select this to enable watchdog timer for Aspeed ast2500/ast2400 devices.
75 The watchdog timer is stopped when initialized. It performs reset, either
76 full SoC reset or CPU or just some peripherals, based on the flags.
77 It currently does not support Boot Flash Addressing Mode Detection or

88 bool "BCM6345 watchdog timer support"
89 depends on WDT && (ARCH_BMIPS || ARCH_BCM6858 || ARCH_BCM63158)
91 Select this to enable watchdog timer for BCM6345 SoCs.
92 The watchdog timer is stopped when initialized.
93 It performs full SoC reset.
96 bool "Cadence watchdog timer support"
100 Select this to enable Cadence watchdog timer, which can be found on some
101 Xilinx Microzed Platform.
104 bool "MPC8xx watchdog timer support"
105 depends on WDT && MPC8xx
106 select CONFIG_MPC8xx_WATCHDOG
108 Select this to enable mpc8xx watchdog timer
111 bool "MediaTek MT7621 watchdog timer support"
112 depends on WDT && SOC_MT7628
114 Select this to enable Ralink / Mediatek watchdog timer,
115 which can be found on some MediaTek chips.
118 bool "MediaTek watchdog timer support"
119 depends on WDT && ARCH_MEDIATEK
121 Select this to enable watchdog timer for MediaTek SoCs.
122 The watchdog timer is stopped when initialized.
123 It performs full SoC reset.

131 Marvell Armada chips.
134 bool "Enable Watchdog Timer support for Sandbox"
135 depends on SANDBOX && WDT
137 Enable Watchdog Timer support in Sandbox. This is a dummy device that
138 can be probed and supports all of the methods of WDT, but does not
