From b73a19e1609d0f705cbab8014ca17aefe89e4c76 Mon Sep 17 00:00:00 2001 From: Yuri Tikhonov Date: Thu, 20 Mar 2008 17:56:04 +0300 Subject: LWMON5: POST RTC fix Modify the RTC API to provide one a status for the time reported by the rtc_get() function: 0 - a reliable time is guaranteed, < 0 - a reliable time isn't guaranteed (power fault, clock issues, and so on). The RTC chip drivers are responsible for providing this info if the corresponding chip supports such functionality. If not - always report that the time is reliable. The POST RTC test was modified to detect the RTC faults utilizing this new rtc_get() feature.
