93 | If you say yes here you get support for various compatible RTC | ||
94 | chips (often with battery backup) connected with I2C. This driver | ||
95 | should handle DS1307, DS1337, DS1338, DS1339, DS1340, ST M41T00, | ||
96 | and probably other chips. In some cases the RTC must already | ||
97 | have been initialized (by manufacturing or a bootloader). | ||
98 | |||
99 | The first seven registers on these chips hold an RTC, and other | ||
100 | registers may add features such as NVRAM, a trickle charger for | ||
101 | the RTC/NVRAM backup power, and alarms. This driver may not | ||
102 | expose all those available chip features. | ||
103 | |||
104 | This driver can also be built as a module. If so, the module | ||
105 | will be called rtc-ds1307. | ||
