+* MSM9625 ASoC Machine driver
+
+Required properties:
+- compatible : "qcom,mdm9625-audio-taiko"
+- qcom,model : The user-visible name of this sound card.
+- qcom,audio-routing : A list of the connections between audio components.
+ Each entry is a pair of strings, the first being the connection's sink,
+ the second being the connection's source.
+- qcom,taiko-mclk-clk-freq : Master clock value given to codec. Some WCD9XXX
+ codec can run at different mclk values. Mclk value can be 9.6MHz or 12.288MHz.
+ This element represents the value for MCLK provided to codec.
+
+Example:
+
+sound {
+ compatible = "qcom,mdm9625-audio-taiko";
+ qcom,model = "mdm9625-taiko-i2s-snd-card";
+
