Generic RTC class support. If you say yes here, you will

probably want to enable one or more of the interfaces below.

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,

|
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.
