Hi Wolfram, I don't think that it's possible to use the generic vbus-supply. In my case the complete chip, not only the bus, is powered by a regulator. In addition it looks like this works only for platform drivers where you can set the bus_regulator before the i2c core probe function is invoked.
Regards, Patrick Rudolph
