Examples are DA9062 and possibly AT91SAM9x. Other things that come to my mind: - move handling of nowayout into the core - some drivers use a reboot notifier. Not sure what they are intended to do there. For i.MX2x it triggers a reboot; for gpio-wdt it tries to stop the watchdog. Of course this doesn't mean this should addressed here. I like the series in general.
