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.

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_ARMADA_37XX 64 bool "Marvell Armada 37xx watchdog timer support" 65 depends on WDT && ARMADA_3700 66 help 67 Enable this to support Watchdog Timer on Marvell Armada 37xx SoC. 68 There are 4 possible clocks which can be used on these SoCs. This 69 driver uses the second clock (ID 1), assuming that so will also 70 Linux's driver. 71 72config WDT_ASPEED 73 bool "Aspeed ast2400/ast2500 watchdog timer support" 74 depends on WDT 75 default y if ARCH_ASPEED 76 help 77 Select this to enable watchdog timer for Aspeed ast2500/ast2400 devices. 78 The watchdog timer is stopped when initialized. It performs reset, either 79 full SoC reset or CPU or just some peripherals, based on the flags. 80 It currently does not support Boot Flash Addressing Mode Detection or 81 Second Boot. 82 83config WDT_BCM6345 84 bool "BCM6345 watchdog timer support" 85 depends on WDT && ARCH_BMIPS 86 help 87 Select this to enable watchdog timer for BCM6345 SoCs. 88 The watchdog timer is stopped when initialized. 89 It performs full SoC reset. 90 91config WDT_ORION 92 bool "Orion watchdog timer support" 93 depends on WDT 94 help 95 Select this to enable Orion watchdog timer, which can be found on some 96 Marvell Armada chips. 97 98config WDT_CDNS 99 bool "Cadence watchdog timer support" 100 depends on WDT 101 imply WATCHDOG 102 help 103 Select this to enable Cadence watchdog timer, which can be found on some 104 Xilinx Microzed Platform. 105 106config XILINX_TB_WATCHDOG 107 bool "Xilinx Axi watchdog timer support" 108 depends on WDT 109 imply WATCHDOG 110 help 111 Select this to enable Xilinx Axi watchdog timer, which can be found on some 112 Xilinx Microblaze Platforms. 113 114config IMX_WATCHDOG 115 bool "Enable Watchdog Timer support for IMX and LSCH2 of NXP" 116 select HW_WATCHDOG 117 help 118 Select this to enable the IMX and LSCH2 of Layerscape watchdog 119 driver. 120 121config WDT_AT91 122 bool "AT91 watchdog timer support" 123 depends on WDT 124 help 125 Select this to enable Microchip watchdog timer, which can be found on 126 some AT91 devices. 127 128config AT91_HW_WDT_TIMEOUT 129 bool "AT91 watchdog timeout specified" 130 depends on WDT_AT91 131 132config WDT_MT7621 133 bool "MediaTek MT7621 watchdog timer support" 134 depends on WDT && ARCH_MT7620 135 help 136 Select this to enable Ralink / Mediatek watchdog timer, 137 which can be found on some MediaTek chips. 138 139endmenu 140
