I using the i2c multiplexer framework, which fits the requirements quite nicely. If anyone happens to know about an existing driver for this chip, please let me know. I would love to get some input for the arbitration mechanism needed to determine if and when to switch bus ownership from one master to the other. Thanks, Guenter
