menuconfig WATCHDOG
	bool "Watchdog Timer Support"
	---help---
	  If you say Y here (and to one of the following options) and create a
	  character special file /dev/watchdog with major number 10 and minor
	  number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
	  subsequently opening the file and then failing to write to it for
	  longer than 1 minute will result in rebooting the machine. This
	  could be useful for a networked machine that needs to come back
	  on-line as fast as possible after a lock-up. There's both a watchdog
	  implementation entirely in software (which can sometimes fail to
	  reboot the machine) and a driver for hardware watchdog boards, which
	  are more robust and can also keep track of the temperature inside
	  your computer. For details, read
	  <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.

	  The watchdog is usually used together with the watchdog daemon
	  which is available from
	  <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
	  also monitor NFS connections and can reboot the machine when the process
	  table is full.

	  If unsure, say N.

config WATCHDOG_CORE
	bool "WatchDog Timer Driver Core"
	---help---
	  Say Y here if you want to use the new watchdog timer driver core.
	  This driver provides a framework for all watchdog timer drivers
	  and gives them the /dev/watchdog interface (and later also the
	  sysfs interface).

config WATCHDOG_NOWAYOUT
	bool "Disable watchdog shutdown on close"
	help
	  The default watchdog behaviour (which you get if you say N here) is
	  to stop the timer if the process managing it closes the file
	  /dev/watchdog. It's always remotely possible that this process might
	  get killed. If you say Y here, the watchdog cannot be stopped once
	  it has been started.

config SOFT_WATCHDOG
	tristate "Software watchdog"
	select WATCHDOG_CORE
	help
	  A software monitoring watchdog. This will fail to reboot your system
	  from some situations that the hardware watchdog will recover
	  from. Equally it's a lot cheaper to install.

	  To compile this driver as a module, choose M here: the
	  module will be called softdog.

config DA9052_WATCHDOG
        tristate "Dialog DA9052 Watchdog"
        depends on PMIC_DA9052
        select WATCHDOG_CORE
        help
          Support for the watchdog in the DA9052 PMIC. Watchdog trigger
          cause system reset.

          Say Y here to include support for the DA9052 watchdog.
          Alternatively say M to compile the driver as a module,
          which will be called da9052_wdt.

config DA9055_WATCHDOG
	tristate "Dialog Semiconductor DA9055 Watchdog"
	depends on MFD_DA9055
	select WATCHDOG_CORE
	help
	  If you say yes here you get support for watchdog on the Dialog
	  Semiconductor DA9055 PMIC.

	  This driver can also be built as a module.  If so, the module
	  will be called da9055_wdt.

config WM831X_WATCHDOG
	tristate "WM831x watchdog"
	depends on MFD_WM831X
	select WATCHDOG_CORE
	help
	  Support for the watchdog in the WM831x AudioPlus PMICs.  When
	  the watchdog triggers the system will be reset.

config WM8350_WATCHDOG
	tristate "WM8350 watchdog"
	depends on MFD_WM8350
	select WATCHDOG_CORE
	help
	  Support for the watchdog in the WM8350 AudioPlus PMIC.  When
	  the watchdog triggers the system will be reset.

config ARM_SP805_WATCHDOG
	tristate "ARM SP805 Watchdog"
	depends on ARM && ARM_AMBA
	select WATCHDOG_CORE
	help
	  ARM Primecell SP805 Watchdog timer. This will reboot your system when
	  the timeout is reached.
