Thanks for your information.

It seems RTC_DRV_DS1374_WDT should be depended on RTC_DRV_DS1374 && WATCHDOG_CORE. Otherwise error will happen if RTC_DRV_DS1374_WDT is enabled but WATCHDOG_CORE not. I'll put this into v5 if there are no other suggestions.

Should I add " Reported-by: Stephen Rothwell <sfr@...b.auug.org.au>" into v5? So many thanks!
