1 I/O channel multiplexer bindings
3 If a multiplexer is used to select which hardware signal is fed to
4 e.g. an ADC channel, these bindings describe that situation.
7 - compatible : "io-channel-mux"
8 - io-channels : Channel node of the parent channel that has multiplexed
10 - io-channel-names : Should be "parent".
11 - #address-cells = <1>;
13 - mux-controls : Mux controller node to use for operating the mux
14 - channels : List of strings, labeling the mux controller states.
16 For each non-empty string in the channels property, an io-channel will
17 be created. The number of this io-channel is the same as the index into
18 the list of strings in the channels property, and also matches the mux
19 controller state. The mux controller state is described in
20 ../mux/mux-controller.txt
