From 12a9ee3cce256ae0f178d604f2c8764fb2942cfe Mon Sep 17 00:00:00 2001 From: Krzysztof Helt Date: Wed, 29 Oct 2008 15:35:24 -0700 Subject: rtc-m48t59: shift zero year to 1968 on sparc (rev 2) Shift the first year to 1968 for Sun SPARC machines. Move this logic from platform specific files to rtc driver as this fixes problems with calculating a century bit. Signed-off-by: Krzysztof Helt Tested-by: Alexander Beregalov Signed-off-by: David S.
