Mark Brown 502a0106b2 [WATCHDOG] Add support for WM831x watchdog 
The WM831x series of devices provide a watchdog with configurable
behaviour on timer expiry.

Currently this driver support refreshes via a register or GPIO line and
autonomous refreshes from a hardware source (eg, a clock).

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.
if WATCHDOG
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.

from. Equally it's a lot cheaper to install.

The Intel Footbridge chip contains a built-in watchdog circuit. Say Y
here if you wish to use this. Alternatively say M to compile the
driver as a module, which will be called wdt285.
This driver does not work on all machines. In particular, early CATS

*Note*: This hardware watchdog is not probeable and thus there
is no way to know if writing to its IO address will corrupt
your system or have any real effect. The only way to be sure
that this driver does what you want is to make sure you
are running it on an EPX-C3 from Winsystems with the watchdog
timer at IO address 0x1ee and 0x1ef. It will write to both those
IO ports. Basically, the assumption is made that if you compile
this driver into your kernel and/or load it as a module, that you
know what you are doing and that you are in fact running on an
EPX-C3 board!

config INDYDOG
tristate "Indy/I2 Hardware Watchdog"
depends on SGI_HAS_INDYDOG
help
Hardware driver for the Indy's/I2's watchdog. This is a

timer expired and no process has written to /dev/watchdog during
that time.
config WDT_MTX1
tristate "MTX-1 Hardware Watchdog"

Watchdog implementation using the GPI hardware found on
PMC-Sierra RM9xxx CPUs.
To compile this driver as a module, choose M here: the
module will be called rm9k_wdt.
config SIBYTE_WDOG
tristate "Sibyte SoC hardware watchdog"
depends on CPU_SB1
help
Watchdog driver for the built in watchdog hardware in Sibyte
SoC processors. There are apparently two watchdog timers
on such processors; this driver supports only the first one,
because currently Linux only supports exporting one watchdog
to userspace.
To compile this driver as a loadable module, choose M here.
The module will be called sb_wdog.

Freescale PowerPC processors. So far this driver supports:
- MPC8xx watchdogs
- MPC83xx watchdogs
- MPC86xx watchdogs
For BookE processors (MPC85xx) use the BOOKE_WDT driver instead.

This driver adds watchdog support for the RTAS watchdog.
To compile this driver as a module, choose M here. The module
will be called wdrtas.
# S390 Architecture
config ZVM_WATCHDOG
tristate "z/VM Watchdog Timer"
depends on S390
help
IBM s/390 and zSeries machines running under z/VM 5.1 or later
provide a virtual watchdog timer to their guest that cause a
user define Control Program command to be executed after a
timeout.
To compile this driver as a module, choose M here. The module
will be called vmwatchdog.
# SUPERH (sh + sh64) Architecture
config SH_WDT
tristate "SuperH Watchdog"
depends on SUPERH && (CPU_SH3 || CPU_SH4)
help
This driver adds watchdog support for the integrated watchdog in the
SuperH processors. If you have one of these processors and wish
to have watchdog support enabled, say Y, otherwise say N.
As a side note, saying Y here will automatically boost HZ to 1000
so that the timer has a chance to clear the overflow counter. On
slower systems (such as the SH-2 and SH-3) this will likely yield
some performance issues. As such, the WDT should be avoided here
unless it is absolutely necessary.
To compile this driver as a module, choose M here: the
module will be called shwdt.
config SH_WDT_MMAP
bool "Allow mmap of SH WDT"
default n
depends on SH_WDT
help
If you say Y here, user applications will be able to mmap the
WDT/CPG registers.

config WATCHDOG_CP1XXX
tristate "CP1XXX Hardware Watchdog support"
depends on SPARC64 && PCI
---help---
This is the driver for the hardware watchdog timers present on
Sun Microsystems CompactPCI models CP1400 and CP1500.
To compile this driver as a module, choose M here: the
module will be called cpwatchdog.
If you do not have a CompactPCI model CP1400 or CP1500, or
another UltraSPARC-IIi-cEngine boardset with hardware watchdog,
you should say N to this option.
config WATCHDOG_RIO
tristate "RIO Hardware Watchdog support"
depends on SPARC64 && PCI
help
Say Y here to support the hardware watchdog capability on Sun RIO
machines. The watchdog timeout period is normally one minute but
can be changed with a boot-time parameter.

config PCWATCHDOG
tristate "Berkshire Products ISA-PC Watchdog"
depends on ISA
---help---
This is the driver for the Berkshire Products ISA-PC Watchdog card.
This card simply watches your kernel to make sure it doesn't freeze,
and if it does, it reboots your computer after a certain amount of
time. This driver is like the WDT501 driver but for different
hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
watchdog cards can be ordered from <http://www.berkprod.com/>.
To compile this driver as a module, choose M here: the
module will be called pcwd.
Most people will say N.
config MIXCOMWD

config WDT
tristate "WDT Watchdog timer"
depends on ISA
---help---
If you have a WDT500P or WDT501P watchdog board, say Y here,
otherwise N. It is not possible to probe for this board, which means
that you have to inform the kernel about the IO port and IRQ that
is needed (you can do this via the io and irq parameters)
To compile this driver as a module, choose M here: the
module will be called wdt.

This is the driver for the Berkshire Products PCI-PC Watchdog card.
This card simply watches your kernel to make sure it doesn't freeze,
and if it does, it reboots your computer after a certain amount of

---help---
If you have a PCI-WDT500/501 watchdog board, say Y here, otherwise N.
If you have a PCI-WDT501 watchdog board then you can enable the
temperature sensor by setting the type parameter to 501.
If you want to enable the Fan Tachometer on the PCI-WDT501, then you
can do this via the tachometer parameter. Only do this if you have a
fan tachometer actually set up.
