My main question is: what is CBUS? It doesn't look like an I2C/SMBUS host controller, but some bit-banging protocol? As such, it shouldn't go to i2c/busses/. And the protocol doesn't look much like I2C, neither. There is no ACK/NACK/START/STOP, so I wonder if it should be in i2c after all...
Jean, maybe you want to have a glimpse on this as well?
