		asoc-wsa-codec-prefixes = "SpkrLeft";

	};

* APQ8009 I2S ASoC Machine driver

Required properties:

- compatible : "qcom,apq8009-audio-i2s-codec"

- qcom,model : The user-visible name of this sound card.

- qcom,pinctrl-names : Lists all the possible combinations of the gpio sets

	mentioned in qcom,msm-gpios. Say we have 2^N combinations for N GPIOs,

	this would list all the 2^N combinations.

- pinctrl-names : The combinations of gpio sets from above that are supported in

	the flavor. This can be sometimes same as qcom,pinctrl-names i.e with 2^N

	combinations or will have less incase if some combination is not supported.

- pinctrl-# : Pinctrl states as mentioned in pinctrl-names.

- qcom,audio-routing : A list of the connections between audio components.

	Each entry is a pair of strings, the first being the connection's sink,

	the second being the connection's source.

Optional properties:

- qcom,cdc-us-euro-gpios : GPIO on which gnd/mic swap signal is coming.

- asoc-platform: This is phandle list containing the references to platform device

		nodes that are used as part of the sound card dai-links.

- asoc-platform-names:  This property contains list of platform names. The order of

			the platform names should match to that of the phandle order

			given in "asoc-platform".

- asoc-cpu: This is phandle list containing the references to cpu dai device nodes

	that are used as part of the sound card dai-links.

- asoc-cpu-names: This property contains list of cpu dai names. The order of the

	cpu dai names should match to that of the phandle order given

	in "asoc-cpu". The cpu names are in the form of "%s.%d" form,

	where the id (%d) field represents the back-end AFE port id that

	this CPU dai is associated with.

- asoc-codec: This is phandle list containing the references to codec dai device

	nodes that are used as part of the sound card dai-links.

- asoc-codec-names: This property contains list of codec dai names. The order of the

		codec dai names should match to that of the phandle order given

		in "asoc-codec".

- qcom,wsa-max-devs : Maximum number of WSA881x devices present in the target

- qcom,wsa-devs: This property contains list of wsa codec names. The names

		should comply with the wsa nodes configurations.

- qcom,wsa-aux-dev-prefix: This property contains list of wsa codec prefixes.
