Description
-----------

i2c-viapro is a true SMBus host driver for motherboards with one of the
supported VIA south bridges.

Your lspci -n listing must show one of these :

 device 1106:3050   (VT82C596A function 3)
 device 1106:3051   (VT82C596B function 3)
 device 1106:3057   (VT82C686 function 4)
 device 1106:3074   (VT8233)
 device 1106:3147   (VT8233A)
 device 1106:8235   (VT8231 function 4)
 device 1106:3177   (VT8235)
 device 1106:3227   (VT8237R)

If none of these show up, you should look in the BIOS for settings like
enable ACPI / SMBus or even USB.

Except for the oldest chips (VT82C596A/B, VT82C686A and most probably
VT8231), this driver supports I2C block transactions. Such transactions
are mainly useful to read from and write to EEPROMs.
