   Different i2c devices will directly talk to i2c core using i2c_transfer().
    If we put this out of the i2c core,the i2c devices like tpsxxxx and etc
    should be registered through the bridge/mux .

     I agree that Grants idea was the cleanest but we may end up in change in
      i2c device probe to register through mux/bridge.(for the
device's connected on that
     particular bus which requires arbitration).
