+* Qualcomm Technologies APQ8096 ASoC sound card driver
+
+This binding describes the APQ8096 sound card, which uses qdsp for audio.
+
+- compatible:
+ Usage: required
+ Value type: <stringlist>
+ Definition: must be "qcom,apq8096-sndcard"
+
+- qcom,audio-routing:
+ Usage: Optional
+ Value type: <stringlist>
+ Definition: 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. Valid names could be power supplies, MicBias
+ of codec and the jacks on the board:
+ Valid names include:
+
+ Board Connectors:
+ "Headphone Left"
+ "Headphone Right"
+ "Earphone"
+ "Line Out1"
+ "Line Out2"
+ "Line Out3"
+ "Line Out4"
+ "Analog Mic1"
+ "Analog Mic2"
+ "Analog Mic3"
+ "Analog Mic4"
+ "Analog Mic5"
+ "Analog Mic6"
+ "Digital Mic2"
+ "Digital Mic3"
+
+ Audio pins and MicBias on WCD9335 Codec:
+ "MIC_BIAS1
+ "MIC_BIAS2"
+ "MIC_BIAS3"
+ "MIC_BIAS4"
+ "AMIC1"
+ "AMIC2"
+ "AMIC3"
+ "AMIC4"
+ "AMIC5"
+ "AMIC6"
+ "AMIC6"
+ "DMIC1"
+ "DMIC2"
+ "DMIC3"
+= dailinks
+Each subnode of sndcard represents either a dailink, and subnodes of each
+dailinks would be cpu/codec/platform dais.
+
+- link-name:
+ Usage: required
+ Value type: <string>
+ Definition: User friendly name for dai link
+
+= CPU, PLATFORM, CODEC dais subnodes
+- cpu:
+ Usage: required
+ Value type: <subnode>
+ Definition: cpu dai sub-node
+
+- codec:
+ Usage: Optional
+ Value type: <subnode>
+ Definition: codec dai sub-node
+
+- platform:
+ Usage: Optional
+ Value type: <subnode>
+ Definition: platform dai sub-node
+
+- sound-dai:
+ Usage: required
+ Value type: <phandle with arguments>
+ Definition: dai phandle/s and port of CPU/CODEC/PLATFORM node.
+
+Example:
+
+audio {
+ compatible = "qcom,apq8096-sndcard";
+ qcom,model = "DB820c";
+
+ mm1-dai-link {
+ link-name = "MultiMedia1";
+ cpu {
+ sound-dai = <&q6asmdai MSM_FRONTEND_DAI_MULTIMEDIA1>;
+ };
+ };
+
+ hdmi-dai-link {
+ link-name = "HDMI Playback";
+ cpu {
+ sound-dai = <&q6afe HDMI_RX>;
+ };
+
+ platform {
+ sound-dai = <&q6adm>;
+ };
+
+ codec {
+ sound-dai = <&hdmi 0>;
+ };
+ };
+};
