The dual nomenclature comes because linux uses i2c throughout the
subsystem, but all the hardware documentation refers to the controller
ASIC in question as 'IIC'.  So I think the convention is that 'i2c' is
used to refer to the type of bus in general, 'iic' is used to refer to
this particular type of bus controller.
