Look at the bus drivers in lm_sensors2/kernel/busses, depending on the
hardware, there are different ways to drive the I2C bus.  But, the
chip drivers (like the lm75) can interface to any (or multiple) bus
drivers because they have the same API.  Does this help?  It think
there is a doc which explains this in the I2C project.
