dt-bindings: soundwire: qcom: Add SoundWire v2.2.0 compatible

2025-12-23T06:44:17+00:00

Add qcom,soundwire-v2.2.0 to the list of supported Qualcomm SoundWire controller versions. This version falls back to qcom,soundwire-v2.0.0 if not explicitly handled by the driver.

dt-bindings: soundwire: qcom: Document v3.1.0 version of IP block

Add bindings for Soundwire controllers v3.1.0, which is available on Qualcomm Glymur SoC.

dt-bindings: soundwire: qcom: deprecate qcom,din/out-ports

2025-12-08T07:07:26+00:00

Number of input and output ports can be dynamically read from the controller registers, getting this value from Device Tree is redundant and potentially lead to bugs. Mark these two properties as deprecated in device tree bindings.

dt-bindings: soundwire: qcom: Document v2.1.0 version of IP block

2025-05-27T19:37:32+00:00

All Qualcomm SoC Soundwire controllers are version-detectable (even 1.x), however certain unidentified quirks might be potentially needed, so document v2.1 version used on Qualcomm SM8650 and SM8750 SoCs, fallbacking to v2.0.

dt-bindings: soundwire: Add reference to soundwire-controller.yaml schema

2023-10-30T21:02:36+00:00

The soundwire-controller.yaml schema already defines the form for devices in child nodes, so there's no need to do the same in the QCom controller binding. Add a $ref to the soundwire-controller.yaml schema and drop the child node schema.

dt-bindings: soundwire: qcom: add 16-bit sample interval

2023-05-08T07:31:34+00:00

The port sample interval was always 16-bit, split into low and high bytes. This split was unnecessary, although harmless for older devices because all of them used only lower byte (so values < 0xff). With support for Soundwire controller on Qualcomm SM8550 and its devices, both bytes will be used, thus add a new 'qcom,ports-sinterval' property to allow 16-bit sample intervals.

dt-bindings: soundwire: qcom: add Qualcomm Soundwire v2.0.0

2023-05-08T07:31:34+00:00

Add compatible for Qualcomm Soundwire v2.0.0 controller, which comes with several differences against v1.7.0 in register layout and more ports (thus increase maxItems of each port-related property to 16).

dt-bindings: Add missing (unevaluated|additional)Properties on child node schemas

2023-04-05T20:38:38+00:00

Just as unevaluatedProperties or additionalProperties are required at the top level of schemas, they should (and will) also be required for child node schemas. That ensures only documented properties are present. Add unevaluatedProperties or additionalProperties as appropriate, and then add any missing properties flagged by the addition.

dt-bindings: soundwire: qcom,soundwire: correct sizes related to number of ports

2023-01-04T00:41:50+00:00

There are several properties depending on number of ports. Some of them had maximum limit of 5 and some of 8. SM8450 AudioReach comes with 8 ports, so fix the limits: sm8450-sony-xperia-nagara-pdx224.dtb: soundwire-controller@3250000: qcom,ports-word-length: 'oneOf' conditional failed, one must be fixed: [[255, 255, 255, 255, 255, 255, 255, 255]] is too short [255, 255, 255, 255, 255, 255, 255, 255] is too long Fixes: febc50b82bc9 ("dt-bindings: soundwire: Convert text bindings to DT Schema") Signed-off-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20221223132159.81211-1-krzysztof.kozlowski@linaro.org Signed-off-by: Rob Herring
