The driver for this RTC device must be loaded before late_initcall
functions run, so it must usually be statically linked.
The first seven registers on these chips hold an RTC, and other
registers may add features such as NVRAM, a trickle charger for

This driver can also be built as a module. If so, the module
will be called rtc-ds1307.

If you say yes here you get support for the RTC on the
- TWL92330 "Menelaus" power mangement chip, used with OMAP2
+ TWL92330 "Menelaus" power management chip, used with OMAP2
platforms. The support is integrated with the rest of
the Menelaus driver; it's not separate module.
