commit 142ef4ca20358703e0dc798c567a885f1d3fb9de Author: Werner Zeh werner.zeh@siemens.com Date: Mon Feb 9 08:17:40 2015 +0100
RTC: Enable RTC reset when power loss was detected.
If function cmos_init() was called with parameter invalid set, this indicates, that the caller has found a power loss event in the RTC registers. In this case, we need to load the default date and time because it can be corrupted.
