           This driver can also be built as a module.  If so, the module
           will be called i2c-i801.

     This driver supports several versions of Intel's I/O Controller Hubs (ICH).
     For SMBus support, they are similar to the PIIX4 and are part
     of Intel's '810' and other chipsets.
