-config RTC_DRV_DS1307
- tristate "Dallas/Maxim DS1307 and similar I2C RTC chips"
- depends on RTC_CLASS && I2C
- 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.

- help
- If you say yes here you get support for the
- Dallas DS1553 timekeeping chip.
-
- This driver can also be built as a module. If so, the module
- will be called rtc-ds1553.

- If you say yes here you get support for the
- Intersil 1208 RTC chip.
