Yay! Thanks for such a quick response.
iicmux0 at simplebus0: GPIO I2C mux
iic3 at iicmux0: I2C bus

It took a bit of time to make it work, b/c of a nasty bug in motoi2c.c
the driver for the parent bus.
struct motoi2c_softc * const sc = device_private(dev);
The problem is that the device here is really imxi2c, so
device_private is imxi2c_softc, not motoi2c_softc! I used a quick
kludge to get the real motoi2c_softc here, but it needs a proper fix.
