+Qualcomm Audio Front End (Q6AFE) binding
+
+AFE is one of the APR audio service on Q6DSP
+Please refer to qcom,apr.txt for details of the common apr service bindings
+used by all apr services.
+
+- but must contain the following property:
+
+- compatible:
+	Usage: required
+	Value type: <stringlist>
+	Definition: must be "qcom,afe-v<MAJOR-NUMBER>.<MINOR-NUMBER>"
+		  Or "qcom,afe" where the version number can be queried
+		  from DSP.
+		  example "qcom,afe-v2.0"
+
+= AFE DAIs (Digial Audio Interface)
+"dais" subnode of the AFE node represents dai specific configuration
+
+- #sound-dai-cells
+	Usage: required
+	Value type: <prop-encoded-array>
+	Definition: Must be 1
+
+- reg
+	Usage: required
+	Value type: <prop-encoded-array>
+	Definition: Must be dai id
+
+- interface-type
+	Usage: required
+	Value type: <stringlist>
+	Definition: Must be one of following
+	"mi2s"
+	"hdmi"
+	"pcm"
+	"slim"
+
+- qcom,sd-lines
+	Usage: required for mi2s interface
+	Value type: <prop-encoded-array>
+	Definition: Must be list of serial data lines used by this dai.
+	should be one or more of the 1-4 sd lines.
