30Description
31-----------
32
33i2c-viapro is a true SMBus host driver for motherboards with one of the
34supported VIA south bridges.
35
36Your /proc/pci or lspci -n listing must show one of these :
37
38 device 1106:3050   (VT82C596A function 3)
39 device 1106:3051   (VT82C596B function 3)
40 device 1106:3057   (VT82C686 function 4)
41 device 1106:3074   (VT8233)
42 device 1106:3147   (VT8233A)
43 device 1106:8235   (VT8231 function 4)
44 device 1106:3177   (VT8235)
45 device 1106:3227   (VT8237R)
46
47If none of these show up, you should look in the BIOS for settings like
48enable ACPI / SMBus or even USB.

50Except for the oldest chips (VT82C596A/B, VT82C686A and most probably
51VT8231), this driver supports I2C block transactions. Such transactions
52are mainly useful to read from and write to EEPROMs.
