14 e.g. an ADC channel, these bindings describe that situation.
16 For each non-empty string in the channels property, an io-channel will be
17 created. The number of this io-channel is the same as the index into the list
18 of strings in the channels property, and also matches the mux controller
19 state. The mux controller state is described in
20 Documentation/devicetree/bindings/mux/mux-controller.yaml
25 const: io-channel-mux
27 io-channels:
29 description: Channel node of the parent channel that has multiplexed input.

40 List of strings, labeling the mux controller states. An empty
41 string for a state means that the channel is not available.
