all devices behind rtciobrg needs a special way to access. currently they are using a platform-specific API. this patch moves to REGMAP, then clients can use regmap APIs to read/write. for the moment, old APIs are still kept, once all clients move to regmap, old APIs will be dropped. this patch also does minor clean for comments, authors statement.

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.

Some DS13XX devices have "trickle chargers". Its configuration register is at different locations, the setup is the same, though. Since the configuration is board specific, introduce a platform_data to this driver. Tested with a DS1339 on a custom board.

Add support for externally mapped ioaddr. This is required on sparc32 as the ioaddr must be mapped with of_ioremap(). Signed-off-by: NKrzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Add support for two compatible RTC: - M48T08 which does not have alarm part, - M48T08 which does not have alarm part and has only 2KB of NVRAM These types covers all Mostek's RTC used in Sun UltraSparc workstations. Tested on Sun Ultra60 with M48T59 RTC.
