[PATCH 2/2] RTC/i.MX/DryIce: add more known register bits
From: Juergen Borleis
Date: Tue Nov 25 2014 - 06:38:07 EST
Intended for monitoring and controlling the security features. These bits are
required to bring this unit back to live after a security violation event was
detected. The code to bring it back to live will follow after a vendor
clearance.
