From c402f8ead68ccd05d63f79ab729184498c3467b3 Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Thu, 17 May 2018 22:20:40 +0200 Subject: rtc: ab-b5ze-s3: let the core handle the RTC range The ab-b5ze-s3 RTC is storing the year in an 8bit bcd coded register so it can handle dates from year 2000 to year 2099.
