The watchdog clock should be disable in dw_wdt_suspend, but we set a dummy clock to watchdog for rk3288. So the watchdog will continue to work during suspend. And we switch the system clock to 32khz from 24Mhz, during suspend, so the watchdog timer over count will increase to 755 times, about 12.5 hours, the original value is 60 seconds. So watchdog will reset the system over a night, but voltage are all incorrect, then it hang on reset.
