Subject: Applied "soc: qcom dt-bindings: Add APR bus bindings" to the asoc tree
The patch
soc: qcom dt-bindings: Add APR bus bindings
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark

+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"
+
+- reg
+ 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.
+
+= EXAMPLE
+The following example represents a QDSP based sound card on a MSM8996 device
+which uses apr as communication between Apps and QDSP.
+
+ apr@4 {
+ compatible = "qcom,apr-v2";
+ reg = <APR_DOMAIN_ADSP>;
