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_. -- Eugene.
