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. 10 11config HW_WATCHDOG 12 bool 13 14config BCM2835_WDT 15 bool "Enable BCM2835/2836 watchdog driver" 16 select HW_WATCHDOG 17 help 18 Say Y here to enable the BCM2835/2836 watchdog 19 20 This provides basic infrastructure to support BCM2835/2836 watchdog 21 hardware, with a max timeout of ~15secs. 22 23config OMAP_WATCHDOG 24 bool "TI OMAP watchdog driver" 25 depends on ARCH_OMAP2PLUS 26 select HW_WATCHDOG 27 default y if AM33XX 28 help 29 Say Y here to enable the OMAP3+ watchdog driver. 30 31config TANGIER_WATCHDOG 32 bool "Intel Tangier watchdog" 33 depends on INTEL_MID 34 select HW_WATCHDOG 35 help 36 This enables support for watchdog controller available on 37 Intel Tangier SoC. If you're using a board with Intel Tangier 38 SoC, say Y here. 39 40config ULP_WATCHDOG 41 bool "i.MX7ULP watchdog" 42 help 43 Say Y here to enable i.MX7ULP watchdog driver. 44 45config WDT 46 bool "Enable driver model for watchdog timer drivers" 47 depends on DM 48 help 49 Enable driver model for watchdog timer. At the moment the API 50 is very simple and only supports four operations: 51 start, restart, stop and reset (expire immediately). 52 What exactly happens when the timer expires is up to a particular 53 device/driver. 54 55config WDT_SANDBOX 56 bool "Enable Watchdog Timer support for Sandbox" 57 depends on SANDBOX && WDT 58 help 59 Enable Watchdog Timer support in Sandbox. This is a dummy device that 60 can be probed and supports all of the methods of WDT, but does not 61 really do anything. 62 63config WDT_ASPEED 64 bool "Aspeed ast2400/ast2500 watchdog timer support" 65 depends on WDT 66 default y if ARCH_ASPEED 67 help 68 Select this to enable watchdog timer for Aspeed ast2500/ast2400 devices. 69 The watchdog timer is stopped when initialized. It performs reset, either 70 full SoC reset or CPU or just some peripherals, based on the flags. 71 It currently does not support Boot Flash Addressing Mode Detection or 72 Second Boot. 73 74config WDT_BCM6345 75 bool "BCM6345 watchdog timer support" 76 depends on WDT && ARCH_BMIPS 77 help 78 Select this to enable watchdog timer for BCM6345 SoCs. 79 The watchdog timer is stopped when initialized. 80 It performs full SoC reset. 81 82config WDT_ORION 83 bool "Orion watchdog timer support" 84 depends on WDT 85 help 86 Select this to enable Orion watchdog timer, which can be found on some 87 Marvell Armada chips. 88 89config WDT_CDNS 90 bool "Cadence watchdog timer support" 91 depends on WDT 92 imply WATCHDOG 93 help 94 Select this to enable Cadence watchdog timer, which can be found on some 95 Xilinx Microzed Platform. 96 97endmenu 98
