From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx>
Straight conversion of the txt file using the mux-consumer.yaml
binding now that is available.
Dropped address-cells and size-cells because there are
not child nodes. Also added mux-control-names as an optional parameter.

-I/O channel multiplexer bindings
-
-If a multiplexer is used to select which hardware signal is fed to
-e.g. an ADC channel, these bindings describe that situation.
-
-Required properties:
-- compatible : "io-channel-mux"
-- io-channels : Channel node of the parent channel that has multiplexed
- input.
-- io-channel-names : Should be "parent".
-- #address-cells = <1>;
-- #size-cells = <0>;
-- mux-controls : Mux controller node to use for operating the mux
-- channels : List of strings, labeling the mux controller states.
-
-For each non-empty string in the channels property, an io-channel will
-be created. The number of this io-channel is the same as the index into
-the list of strings in the channels property, and also matches the mux
-controller state. The mux controller state is described in
-../mux/mux-controller.yaml
-
-Example:
- mux: mux-controller {
- compatible = "gpio-mux";
- #mux-control-cells = <0>;
-
- mux-gpios = <&pioA 0 GPIO_ACTIVE_HIGH>,
- <&pioA 1 GPIO_ACTIVE_HIGH>;
- };
-
- adc-mux {
- compatible = "io-channel-mux";
- io-channels = <&adc 0>;
- io-channel-names = "parent";
-
- mux-controls = <&mux>;
-
- channels = "sync", "in", "system-regulator";
- };
