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.

select WATCHDOG_CORE
help
ARM Primecell SP805 Watchdog timer. This will reboot your system when
the timeout is reached.
config AT91RM9200_WATCHDOG
tristate "AT91RM9200 watchdog"
depends on ARCH_AT91RM9200
help
Watchdog timer embedded into AT91RM9200 chips. This will reboot your
system when the timeout is reached.
