help
Enabling this option will add specific SMBus support for the Tyan
S4882 motherboard. On this 4-CPU board, the SMBus is multiplexed
over 8 different channels, where the various memory module EEPROMs
and temperature sensors live. Saying yes here will give you access
to these in addition to the trunk.
This driver can also be built as a module. If so, the module
will be called i2c-amd756-s4882.
