+Required properties:
+- compatible : "qcom,sdx-asoc-snd-tavil"
+- qcom,model : The user-visible name of this sound card.
+- qcom,prim_mi2s_aux_master : Handle to prim_master pinctrl configurations
+- qcom,prim_mi2s_aux_slave : Handle to prim_slave pinctrl configurations
+- qcom,sec_mi2s_aux_master : Handle to sec_master pinctrl configurations
+- qcom,sec_mi2s_aux_slave : Handle to sec_slave pinctrl configurations
+- 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 give
+		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.
