This chip has two modes to control secondary sensor attached to it.
One is master mode and another is bypass mode. In master mode
MPU6500 will directly communicates to the secondary sensor device
attached to it. This can support very few secondary devices in this
mode.
But when configured in bypass mode the i2c lines are directly connected
to host i2c bus controller.
Since in master mode it can only support few devices and they are not
implemented in this driver, set the default mode to bypass mode.

This has been proposed before by Manuel Stahl,
Please read the thread from
http://www.spinics.net/lists/linux-iio/msg11985.html
In short, the best way we have come up with for handling this cleanly
(avoiding issues with the device in between going into sleep etc) was
to implement an i2c bus multiplexer with 1 input and 1 output as part of
the driver.
Manuel, any progress on your patches?
No, I was waiting for the outcome of this discussion. Probably I will
not be available for the next three weeks, so if someone else wants to
start off coding, feel free to do so.
