-where they do strange things compared to the other drivers.
-
-acquirewdt.c -- Acquire Single Board Computer
-
-	This driver has a hardcoded timeout of 1 minute
-
-	Supports CONFIG_WATCHDOG_NOWAYOUT
-
-	GETSUPPORT returns KEEPALIVEPING.  GETSTATUS will return 1 if
-	the device is open, 0 if not.  [FIXME -- isn't this rather
-	silly?  To be able to use the ioctl, the device must be open
-	and so GETSTATUS will always return 1].
-
-advantechwdt.c -- Advantech Single Board Computer
-
-	Timeout that defaults to 60 seconds, supports SETTIMEOUT.
-
-	Supports CONFIG_WATCHDOG_NOWAYOUT
-
-	GETSUPPORT returns WDIOF_KEEPALIVEPING and WDIOF_SETTIMEOUT.
-	The GETSTATUS call returns if the device is open or not.
-	[FIXME -- silliness again?]
-	
-booke_wdt.c -- PowerPC BookE Watchdog Timer
-
-	Timeout default varies according to frequency, supports
-	SETTIMEOUT
-
-	Watchdog cannot be turned off, CONFIG_WATCHDOG_NOWAYOUT
-	does not make sense
-
-	GETSUPPORT returns the watchdog_info struct, and
-	GETSTATUS returns the supported options. GETBOOTSTATUS
-	returns a 1 if the last reset was caused by the
-	watchdog and a 0 otherwise. This watchdog cannot be
-	disabled once it has been started. The wdt_period kernel
-	parameter selects which bit of the time base changing
-	from 0->1 will trigger the watchdog exception. Changing
-	the timeout from the ioctl calls will change the
-	wdt_period as defined above. Finally if you would like to
-	replace the default Watchdog Handler you can implement the
-	WatchdogHandler() function in your own code.
-
-eurotechwdt.c -- Eurotech CPU-1220/1410
-
-	The timeout can be set using the SETTIMEOUT ioctl and defaults
-	to 60 seconds.

-	Also has a module parameter "ev", event type which controls
-	what should happen on a timeout, the string "int" or anything
-	else that causes a reboot.  [FIXME -- better description]
-
-	Supports CONFIG_WATCHDOG_NOWAYOUT
-
-	GETSUPPORT returns CARDRESET and WDIOF_SETTIMEOUT but

-i810-tco.c -- Intel 810 chipset
-
-	Also has support for a lot of other i8x0 stuff, but the
-	watchdog is one of the things.

-	Watchdog Timer Interfaces For The Linux Operating System
-

-	     Custom Linux Driver And Program Development
-
-
-The following watchdog drivers are currently implemented:
-
-	ICS	WDT501-P
-	ICS	WDT501-P (no fan tachometer)
-	ICS	WDT500-P
-	Software Only
-	SA1100 Internal Watchdog
-	Berkshire Products PC Watchdog Revision A & C (by Ken Hollis)
-
-
-All six interfaces provide /dev/watchdog, which when open must be written
-to within a timeout or the machine will reboot. Each write delays the reboot
-time another timeout. In the case of the software watchdog the ability to 
-reboot will depend on the state of the machines and interrupts. The hardware
-boards physically pull the machine down off their own onboard timers and
-will reboot from almost anything.
-
-A second temperature monitoring interface is available on the WDT501P cards
-and some Berkshire cards. This provides /dev/temperature. This is the machine 
-internal temperature in degrees Fahrenheit. Each read returns a single byte 
-giving the temperature.
-
-The third interface logs kernel messages on additional alert events.
-
-Both software and hardware watchdog drivers are available in the standard
-kernel. If you are using the software watchdog, you probably also want
-to use "panic=60" as a boot argument as well.
-
-The wdt card cannot be safely probed for. Instead you need to pass
-wdt=ioaddr,irq as a boot parameter - eg "wdt=0x240,11".
-
-The SA1100 watchdog module can be configured with the "sa1100_margin"
-commandline argument which specifies timeout value in seconds.
-
-The i810 TCO watchdog modules can be configured with the "i810_margin"
-commandline argument which specifies the counter initial value. The counter
-is decremented every 0.6 seconds and default to 50 (30 seconds). Values can
-range between 3 and 63.
-
-The i810 TCO watchdog driver also implements the WDIOC_GETSTATUS and
-WDIOC_GETBOOTSTATUS ioctl()s. WDIOC_GETSTATUS returns the actual counter value
-and WDIOC_GETBOOTSTATUS returns the value of TCO2 Status Register (see Intel's
-documentation for the 82801AA and 82801AB datasheet).
