From 8fc2c767b06067b417c565c4e75731e68ed41fd8 Mon Sep 17 00:00:00 2001 From: "Kim B. Heino" Date: Wed, 23 Jul 2008 21:30:34 -0700 Subject: rtc: add support for ST M41T94 SPI RTC This patch adds kernel driver for M41T94 RTC chip connected via SPI. I've tested it on two different AT91-based hardwares. This is third revision of the patch: some comments made by Alessandro Zummo fixed. Revision two added support for century bit and fixes.
