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. 37 38config WDT_SANDBOX 39 bool "Enable Watchdog Timer support for Sandbox" 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. 45 46config WDT_ASPEED 47 bool "Aspeed ast2400/ast2500 watchdog timer support" 48 depends on WDT 49 default y if ARCH_ASPEED 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. 56 57config WDT_BCM6345 58 bool "BCM6345 watchdog timer support" 59 depends on WDT && ARCH_BMIPS 60 help 61 Select this to enable watchdog timer for BCM6345 SoCs. 62 The watchdog timer is stopped when initialized. 63 It performs full SoC reset. 64 65endmenu 66
