Right, but I think, there are some i2c ICs, that allow for address translations. Don't remember what they are called, some multiplexers or some such. > Now you talk about the .power() callback, I could use it so that the > multiplexer is managed by it, using a similar mechanism as in mach-migor.

I will give it a try (hoping that this also works at driver > registering ... we will see). Don't think it would work, at least not with the current stack. With the new stack video devices are registered at host-driver registration time, after i2c devices are registered. It wouldn't work with the old stack either.
