From aaaf5fbf56f16c81a653713cc333b18ad6e25ea9 Mon Sep 17 00:00:00 2001 From: Joshua Kinard Date: Mon, 16 Feb 2015 16:00:26 -0800 Subject: rtc: add driver for DS1685 family of real time clocks This adds a driver for the Dallas/Maxim DS1685-family of RTC chips. It supports the DS1685/DS1687, DS1688/DS1691, DS1689/DS1693, DS17285/DS17287, DS17485/DS17487, and DS17885/DS17887 RTC chips. These chips are commonly found in SGI O2 and SGI Octane systems. It was originally derived from a driver patch submitted by Matthias Fuchs many years ago for use in EPPC-405-UC modules, which also used these RTCs. In addition to the time-keeping functions, this RTC also handles the shutdown mechanism of the O2 and Octane and acts as a partial NVRAM for the boot PROMS in these systems. Verified on both an SGI O2 and an SGI Octane.
