+ help
+ If you say yes here you get support for various compatible RTC
+ chips (often with battery backup) connected with I2C. This driver
+ should handle DS1307, DS1337, DS1338, DS1339, DS1340, ST M41T00,
+ and probably other chips. In some cases the RTC must already
+ have been initialized (by manufacturing or a bootloader).
+
+ The first seven registers on these chips hold an RTC, and other
+ registers may add features such as NVRAM, a trickle charger for
+ the RTC/NVRAM backup power, and alarms. This driver may not
+ expose all those available chip features.
+
+ This driver can also be built as a module. If so, the module
+ will be called rtc-ds1307.
