-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-v<VERSION-NUMBER>", example "qcom,apr-v2"
-
-- qcom,apr-domain
-	Usage: required
-	Value type: <u32>
-	Definition: Destination processor ID.
-	Possible values are :
-			1 - APR simulator
-			2 - PC
-			3 - MODEM
-			4 - ADSP
-			5 - APPS
-			6 - MODEM2
-			7 - APPS2
-
-= APR SERVICES
-Each subnode of the APR node represents service tied to this apr. The name
-of the nodes are not important. The properties of these nodes are defined
-by the individual bindings for the specific service
-- All APR services MUST contain the following property:
-
-- reg
-	Usage: required
-	Value type: <u32>
-	Definition: APR Service ID
-	Possible values are :
-			3 - DSP Core Service
-			4 - Audio Front End Service.
-			5 - Voice Stream Manager Service.
-			6 - Voice processing manager.
-			7 - Audio Stream Manager Service.
-			8 - Audio Device Manager Service.
-			9 - Multimode voice manager.
-			10 - Core voice stream.
-			11 - Core voice processor.
-			12 - Ultrasound stream manager.
-			13 - Listen stream manager.
-
-- qcom,protection-domain
-	Usage: optional
-	Value type: <stringlist>
-	Definition: Must list the protection domain service name and path
-		    that the particular apr service has a dependency on.
-	Possible values are :
-			"avs/audio", "msm/adsp/audio_pd".
-			"kernel/elf_loader", "msm/modem/wlan_pd".
-			"tms/servreg", "msm/adsp/audio_pd".
-			"tms/servreg", "msm/modem/wlan_pd".
-			"tms/servreg", "msm/slpi/sensor_pd".
-
-= 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-v2";
-		qcom,apr-domain = <APR_DOMAIN_ADSP>;
-
-		apr-service@3 {
-			compatible = "qcom,q6core";
-			reg = <APR_SVC_ADSP_CORE>;
-		};
-
-		apr-service@4 {
-			compatible = "qcom,q6afe";
-			reg = <APR_SVC_AFE>;
-
-			dais {
-				#sound-dai-cells = <1>;
-				dai@1 {
-					reg = <HDMI_RX>;
-				};
-			};
-		};
-
-		apr-service@7 {
-			compatible = "qcom,q6asm";
-			reg = <APR_SVC_ASM>;
-			...
-		};
-
-		apr-service@8 {
-			compatible = "qcom,q6adm";
-			reg = <APR_SVC_ADM>;
-			...
-		};
-	};
-
-= EXAMPLE 2
-The following example represents a QDSP based sound card with protection domain
-dependencies specified. Here some of the apr services are dependent on services
-running on protection domain hosted on ADSP/SLPI remote processors while others
-have no such dependency.
-
-	apr {
-		compatible = "qcom,apr-v2";
-		qcom,glink-channels = "apr_audio_svc";

-			reg = <APR_SVC_ADSP_CORE>;
-		};

-		q6afe: apr-service@4 {
-			compatible = "qcom,q6afe";
-			reg = <APR_SVC_AFE>;
-			qcom,protection-domain = "avs/audio", "msm/adsp/audio_pd";

-		};
