37 to both the positive and negative inputs of a differential ADC.
40 There are also some ADCs, where the differential channel has dedicated
41 positive and negative inputs which can be used to measure differential
43 the 'reg' property for both inputs (i.e. diff-channels = <reg reg>).
45 single-channel:
48 When devices combine single-ended and differential channels, allow the
50 differential channels). If this and diff-channels are not present reg
53 common-mode-channel:
56 Some ADCs have differential input pins that can be used to measure
57 single-ended or pseudo-differential inputs. This property can be used
58 in addition to single-channel to signal software that this channel is
59 not differential but still specify two inputs.
61 The input pair is specified by setting single-channel to the positive
62 input pin and common-mode-channel to the negative pin.

68 oversampling-ratio:
71 Oversampling is used as replacement of or addition to the low-pass filter.
