        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 <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.

if I2C

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 <file:Documentation/i2c/dev-interface>.

          This support is also available as a module.  If so, the module 
          will be called i2c-dev.

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