I2C support
CONFIG_I2C
  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.
  Specifically, if you want to use a BT848 based frame grabber/overlay
  boards under Linux, say Y here and also to "I2C bit-banging
  interfaces", below.

  If you want I2C support, you should say Y here and also to the
  specific driver for your bus adapter(s) below.  If you say Y to
  "/proc file system" below, you will then get a /proc interface which
  is documented in <file:Documentation/i2c/proc-interface>.

  This I2C support is also available as a module.  If you want to
  compile it as a module, say M here and read
  <file:Documentation/modules.txt>.
  The module will be called i2c-core.o.
