NAME

     smbus - System Management Bus controller driver

DESCRIPTION

     The smbus driver is a  I2C  (Inter  IC)  nexus  driver  that
     allows   the  system  to  communicate  with  various  system
     component chips. SMBus is a two-wire control  bus  based  on
     the  I2C protocol through which systems can communicate with
     various I2C devices connected to the bus.

     The smbus driver supports  byte  and  block  level  transfer
     based on interrupt and polled mode.
