Stephan Gerhold	f49176fb13	dt-bindings: soc: qcom: apr: Use generic node names for APR services ... Device nodes should be named according to the class of devices they belong to. Change the suggested names of the subnodes to apr-service@<id>, which is already in use in arch/arm64/boot/dts/qcom/sdm845.dtsi.

Sibi Sankar	a03a5b6313	dt-bindings: soc: qcom: apr: Add protection domain bindings ... Qualcomm SoCs (starting with MSM8998) allow for multiple protection domains (PDs) to run on the same Q6 sub-system. This allows for services like AVS AUDIO to have their own separate address space and crash/recover without disrupting the other PDs running on the same Q6 ADSP. Add "qcom,protection-domain" bindings to capture the dependencies between the APR service and the PD on which the apr service runs.

Bjorn Andersson	70d22b78d3	soc: qcom: apr: Don't use reg for domain id ... The reg property represents the address and size on the bus that a device lives, but for APR the parent is a rpmsg bus, which does not have numerical addresses. Simply defining #address/#size-cells to 1 and 0, respectively, to silence the compiler is not an appropriate solution. Replace the use of "reg" with an APR specific property.

Srinivas Kandagatla	8675e8d3d1	soc: qcom dt-bindings: Add APR bus bindings ... This patch add dt bindings for Qualcomm APR (Asynchronous Packet Router) bus driver. This bus is used for communicating with DSP which provides audio and various other services to cpu.
