+* Qualcomm Technologies APQ8016 SBC ASoC machine driver
+
+This node models the Qualcomm Technologies APQ8016 SBC ASoC machine driver
+
+Required properties:
+
+- compatible : "qcom,apq8016-sbc-sndcard"
+
+- pinctrl-N : One property must exist for each entry in
+ pinctrl-names. See ../pinctrl/pinctrl-bindings.txt
+ for details of the property values.
+- pinctrl-names : Must contain a "default" entry.
+- reg : Must contain an address for each entry in reg-names.
+- reg-names : A list which must include the following entries:
+ * "mic-iomux"
+ * "spkr-iomux"
+- qcom,model : Name of the sound card.
+
+Dai-link subnode properties and subnodes:
+
+Required dai-link subnodes:
+
+- cpu : CPU sub-node
+- codec : CODEC sub-node
+
+Required CPU/CODEC subnodes properties:
+
+-link-name : Name of the dai link.
+-sound-dai : phandle and port of CPU/CODEC
+-capture-dai : phandle and port of CPU/CODEC
+
+Example:
+
+sound: sound {
