I apologize I missed this. These were going to be mux controls for two
differential inputs. There are two inputs, but only one can be used at

remove the mux controls since it is likely just going to be noise to
anybody configuring the chip through these controls.

Good point. In the next version the callbacks will be implied through
the use of the macro.

improve the driver.
