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 Watchdog Timer support for IMX and LSCH2 of NXP"
22 select HW_WATCHDOG if !WDT

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

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

79 depends on WDT && (ARCH_BMIPS || ARCH_BCM6858 || ARCH_BCM63158)
81 Select this to enable watchdog timer for BCM6345 SoCs.
82 The watchdog timer is stopped when initialized.
83 It performs full SoC reset.
86 bool "Cadence watchdog timer support"
90 Select this to enable Cadence watchdog timer, which can be found on some
91 Xilinx Microzed Platform.
94 bool "MPC8xx watchdog timer support"
95 depends on WDT && MPC8xx
96 select CONFIG_MPC8xx_WATCHDOG
98 Select this to enable mpc8xx watchdog timer
101 bool "MediaTek MT7621 watchdog timer support"
102 depends on WDT && SOC_MT7628
104 Select this to enable Ralink / Mediatek watchdog timer,
105 which can be found on some MediaTek chips.
108 bool "MediaTek watchdog timer support"
109 depends on WDT && ARCH_MEDIATEK
111 Select this to enable watchdog timer for MediaTek SoCs.
112 The watchdog timer is stopped when initialized.
113 It performs full SoC reset.
116 bool "TI OMAP watchdog timer support"
117 depends on WDT && ARCH_OMAP2PLUS
120 This enables OMAP3+ watchdog timer driver, which can be
121 found on some TI chipsets and inline with driver model.
124 bool "Orion watchdog timer support"
