+Qualcomm APR (Asynchronous Packet Router) binding
+
+This binding describes the Qualcomm APR. APR is a IPC protocol for
+communication between Application processor and QDSP. APR is mainly
+used for audio/voice services on the QDSP.
+
+- compatible:
+ Usage: required
+ Value type: <stringlist>
+ Definition: must be "qcom,apr-<SOC-NAME>" example: "qcom,apr-msm8996"
+
+
+- qcom,smd-channel:
+ Usage: required
+ Value type: <string>
+ Definition: standard SMD property specifying the SMD channel used for
+ communication with the APR on QDSP.
+ Should be "apr_audio_svc".
+ Described in soc/qcom/qcom,smd.txt
+
+= EXAMPLE
+The following example represents a QDSP based sound card on a MSM8996 device
+which uses apr as communication between Apps and QDSP.
+
+ apr {
+ compatible = "qcom,apr-msm8996";
+ qcom,smd-channels = "apr_audio_svc";
+ };
