Heck I gave it a try and attached you'll find a patch to add F71889FG support to the current f71808e_wdt watchdog driver. The reason I haven't send this to the LKML before however, is that I don't have any system with that chip to test it, so please do test it and tell me the results. -- Met vriendelijke groet, With kind regards, Giel van Schijndel -- "It would seem that perfection is attained not when no more can be added, but when no more can be removed." -- Antoine de Saint Exupéry
