This RTC is used in some Calao boards. The driver code is taken from
the linux rtc-m41t94 driver

Several source files need to be compiled and linked when one or more
config options are selected. To allow for easy selection in the
Makefiles yet to avoild multiple compilation (which costs build time)
and especially multiple linking (which causes errors), we use
"COBJS = $(sort COBJS-y)" which eliminates duplicates.
By courtesy of Detlev Zundel who suggested this approach.

This "||" doesn't seem to work. Now using the idea suggest by Scott Wood
to combine both config options into one line. This even allows defining
both options and not generating the target object twice.

MC13783 is a multifunction IS with an SPI interface to the host. This
driver handles the RTC controller in this chip.

This patch add support for the STM M41T62 RTC. It is used and tested
on the AMCC Canyonlands 406EX platform.

This driver is based on the driver for the M41T11. In the intended
application, the RTC will be powered by a large capacitor, rather than a
battery. The driver therefore checks to see whether the RTC has lost
power. The chip's OUT bit is normally reset from its power-up state. If
the OUT bit is read as set, or if the date and time are not valid, then the
RTC is assumed to have lost power, and its date and time are reset to
1900-01-01 00:00:00.
Support for adjusting the speed of the clock to improve accuracy is
provided through an environment variable.
