From: Sebastian Krzyszkowiak <sebastian.krzyszkowiak@puri.sm> It has been disabled because it was being used for system clock instead of the discrete RTC. However, SNVS has some features that the discrete RTC does not, such as being able to turn the device on. Solve that issue with aliases instead and reenable SNVS RTC.
