+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. Must contain the following properties.
+
+- compatible:
+ Usage: required
+ Value type: <stringlist>
+ Definition: must be "qcom,q6afe-v<MAJOR-NUMBER>.<MINOR-NUMBER>"
+ Or "qcom,q6afe" where the version number can be queried
+ from DSP.
+ example "qcom,q6afe"
+
+= AFE DAIs (Digial Audio Interface)
+"dais" subnode of the AFE node. It represents afe dais, each afe dai is a
+subnode of "dais" representing board specific dai setup.
+"dais" node should have following properties followed by dai children.
+
+- #sound-dai-cells
+ Usage: required
+ Value type: <u32>
+ Definition: Must be 1
+
+- #address-cells
+ Usage: required
+ Value type: <u32>
+ Definition: Must be 1
+
+- #size-cells
+ Usage: required
+ Value type: <u32>
+ Definition: Must be 0
+
+== AFE DAI is subnode of "dais" and represent a dai, it includes board specific
+configuration of each dai. Must contain the following properties.
+
+- reg
+ Usage: required
+ Value type: <u32>
+ Definition: Must be dai id
+
+- 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.
