From ad89f87a84040a57c4a78ca2759b364f72f423ab Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Fri, 3 Aug 2007 14:19:58 +0900 Subject: rtc: rtc-sh: Support 4-digit year on SH7705/SH7710/SH7712. All SH-4 parts have a 4-digit year, while the SH-3 parts typically only use a 2-digit one. The SH7705, SH7710, and SH7712 SH-3 parts however opted to extend it to 4-digit and still look and act like an SH-3 RTC in all other ways. This adds a capability flag (RTC_CAP_4_DIGIT_YEAR) that these corner-case CPU subtypes can set in their platform data and cleans up some of the ifdef mess in the driver as a result.
