+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.
