Philips' documentation uses I2C, not IIC, so I guess this is 
_official_ name of the _bus_.

Some vendors (like IBM in their 4xx parts) use IIC to name I2C 
_interface_ to distinguish it from I2C _bus_ (they specifically 
mention this in the chip manual).

For example, in the corresponding 4xx driver I used "iic" because it 
was written for IBM IIC _interface_.
