From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx> Binding covering the ad7150, ad7151 and ad7156 capacitance to digital convertors. The only difference between these is how many channels they have (1 or 2) Whilst it is clearly necessary to provide power to the part, we don't need to know the voltage or anything so if it is always on, there should be no need to have it specified in the binding.
