- *  20000710 Nils Faerber
- *	Initial Version 0.01
- *  20000728 Nils Faerber
- *	0.02 Fix for SMI_EN->TCO_EN bit, some cleanups
- *  20011214 Matt Domsch <Matt_Domsch@dell.com>
- *	0.03 Added nowayout module option to override CONFIG_WATCHDOG_NOWAYOUT
- *	     Didn't add timeout option as i810_margin already exists.
- *  20020224 Joel Becker, Wim Van Sebroeck
- *	0.04 Support for 82801CA(M) chipset, timer margin needs to be > 3,
- *	     add support for WDIOC_SETTIMEOUT and WDIOC_GETTIMEOUT.
- *  20020412 Rob Radez <rob@osinvestor.com>, Wim Van Sebroeck
- *	0.05 Fix possible timer_alive race, add expect close support,
- *	     clean up ioctls (WDIOC_GETSTATUS, WDIOC_GETBOOTSTATUS and
- *	     WDIOC_SETOPTIONS), made i810tco_getdevice __init,
- *	     removed boot_status, removed tco_timer_read,
- *	     added support for 82801DB and 82801E chipset,
- *	     added support for 82801EB and 8280ER chipset,
- *	     general cleanup.
- *  20030921 Wim Van Sebroeck <wim@iguana.be>
- *	0.06 change i810_margin to heartbeat, use module_param,
- *	     added notify system support, renamed module to i8xx_tco.
- *  20050128 Wim Van Sebroeck <wim@iguana.be>
- *	0.07 Added support for the ICH4-M, ICH6, ICH6R, ICH6-M, ICH6W and ICH6RW
- *	     chipsets. Also added support for the "undocumented" ICH7 chipset.
- *  20050807 Wim Van Sebroeck <wim@iguana.be>
- *	0.08 Make sure that the watchdog is only "armed" when started.
- *	     (Kernel Bug 4251)
- *  20060416 Wim Van Sebroeck <wim@iguana.be>
- *	0.09 Remove support for the ICH6, ICH6R, ICH6-M, ICH6W and ICH6RW and
- *	     ICH7 chipsets. (See Kernel Bug 6031 - other code will support these
- *	     chipsets)
