If you say yes to this option, support will be included for the VIA
82C596/82C686/823x I2C interfaces. Specifically, the following
82C596/82C686/82xx I2C interfaces. Specifically, the following
chipsets are supported:
82C596A/B
82C686A/B
8231

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