I see. The ppc_md.heartbeat facility isn't going anywhere as there are multiple users. It's possible to take the "ppc405_wdt" driver with a rename and minor cleanup have it be a generic timebase driven watchdog driver that is compliant with the familiar WD interface. What do you see as the advantage to having a watchdog driver that uses the booke hardware watchdog facility over a generic timebase driven driver? -Matt
