175 diff-channels:
178 The ADC uses the same positive and negative inputs for this.
180 both positive and negative inputs (i.e. diff-channels = <reg reg>).
189 The ADC channels can be configured as
190 * Bipolar single-ended
191 * Unipolar single-ended
194 'unipolar single-ended'. So for the other configurations the 'bipolar'
195 property must be specified. If 'diff-channels' is specified, it is
197 single-ended.
