CONFIG_I2C: I2C support

General informations

The Linux kernel configuration item CONFIG_I2C:

Help text

I2C (pronounce: I-squared-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 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.
