Audio complex for Eukrea boards with tlv320aic23 codec. Required properties: - compatible : "eukrea,asoc-tlv320" - eukrea,model : The user-visible name of this sound complex. - ssi-controller : The phandle of the SSI controller. - fsl,mux-int-port : The internal port of the i.MX audio muxer (AUDMUX). - fsl,mux-ext-port : The external port of the i.MX audio muxer. Note: The AUDMUX port numbering should start at 1, which is consistent with hardware manual. Example: sound { compatible = "eukrea,asoc-tlv320"; eukrea,model = "imx51-eukrea-tlv320aic23"; ssi-controller = <&ssi2>; fsl,mux-int-port = <2>; fsl,mux-ext-port = <3>; };
