        tristate "I2C support"

        depends on HAS_IOMEM

        ---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 ,

          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_BOARDINFO

        boolean

        default y

config I2C_CHARDEV

        tristate "I2C device interface"

        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 .

          This support is also available as a module.  If so, the module

          will be called i2c-dev.

          Say Y here if you want the I2C core to produce a bunch of debug

          messages to the system log.  Select this if you are having a
