I think simple devices might have been agreed upon (but it's been a

I posted something in one of the i2c device tree threads a while ago:

Basically, you just have a node that is both an i2c device and an i2c
controller, and the mux driver binds to it and registers the subordinate
buses as new i2c controllers.
