7 title: Generic IIO bindings for ADC channels

13 A few properties are defined in a common way ADC channels.
17 pattern: "^channel(@[0-9a-f]+)?$"
19 A channel index should match reg.

30 description: If provided, the channel is to be used in bipolar mode.

37 Many ADCs have dual Muxes to allow different input pins to be routed
38 to both the positive and negative inputs of a differential ADC.
39 The first value specifies the positive input pin, the second
40 specifies the negative input pin.
44 Time between enabling the channel and first stable readings.

49 Oversampling is used as replacement of or addition to the low-pass filter.
50 In some cases, the desired filtering characteristics are a function the
51 device design and can interact with other characteristics such as
