patch 1 and 2 can be merge as single patch.

generic comment, we have proper watchdog framework where we can have 
some api for watchdog_ops and register as watchdog_register_device().
Then core parts take care of the all fileops/sysfs interface.
This need not to be develop locally.

You can refer wm831x_wdt.c, wm8350_wdt.c driver for more reference where 
it is really used watchdog framework.


I think you can use the watchdog framework for this.
