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
