+config I2C
+ tristate "I2C support"
+ ---help---
+ I2C (pronounce: I-square-C) is a slow serial bus protocol used in
+ many micro controller applications and developed by Philips. SMBus,
+ or System Management Bus is a subset of the I2C protocol. More
+ information is contained in the directory <file:Documentation/i2c/>,
+ especially in the file called "summary" there.
+
+ Both I2C and SMBus are supported here. You will need this for
+ hardware sensors support, and also for Video For Linux support.
+
+ If you want I2C support, you should say Y here and also to the
+ specific driver for your bus adapter(s) below.
+
+ This I2C support can also be built as a module. If so, the module
+ will be called i2c-core.
+
+config I2C_CHARDEV
+ tristate "I2C device interface"
+ depends on I2C
+ help
+ Say Y here to use i2c-* device files, usually found in the /dev
+ directory on your system. They make it possible to have user-space
+ programs use the I2C bus. Information on how to do this is
+ contained in the file <file:Documentation/i2c/dev-interface>.
+
+ This support is also available as a module. If so, the module
+ will be called i2c-dev.
