- * MixCom Watchdog: A Simple Hardware Watchdog Device
- * Based on Softdog driver by Alan Cox and PC Watchdog driver by Ken Hollis
- *

- *
- * Version 0.1 (99/04/15):
- *		- first version
- *
- * Version 0.2 (99/06/16):
- *		- added kernel timer watchdog ping after close
- *		  since the hardware does not support watchdog shutdown
- *
- * Version 0.3 (99/06/21):
- *		- added WDIOC_GETSTATUS and WDIOC_GETSUPPORT ioctl calls
- *
- * Version 0.3.1 (99/06/22):
- *		- allow module removal while internal timer is active,
- *		  print warning about probable reset
- *
- * Version 0.4 (99/11/15):
- *		- support for one more type board
- *
- * Version 0.5 (2001/12/14) Matt Domsch <Matt_Domsch@dell.com>
- *		- added nowayout module option to override CONFIG_WATCHDOG_NOWAYOUT
- *
- * Version 0.6 (2002/04/12): Rob Radez <rob@osinvestor.com>
- *		- make mixcomwd_opened unsigned,
- *		  removed lock_kernel/unlock_kernel from mixcomwd_release,
- *		  modified ioctl a bit to conform to API
