[PATCH v3 0/3] arm64: dts: qcom: sm8750: Add sound

[Krzysztof Kozlowski]

Changes in v3:
- Add vdd-px-supply to audio-codec node
- Add tags
- New patch #3 for QRD8750.
- Link to v2: https://lore.kernel.org/r/20250519-sm8750-audio-part-2-v2-0-5ac5afdf4ee2@linaro.org

Changes in v2:
- Patch #1:
  - Use v2.1 compatible with v2.0 fallback (Konrad)
  - Use hex address in <reg>
  - Re-order nodes to keep proper sorting by unit address
- Patch #2:
  - Re-order codec/cpu nodes (Konrad)
- Link to v1: https://lore.kernel.org/r/20250424-sm8750-audio-part-2-v1-0-50133a0ec35f@linaro.org

Bindings for the new Soundwire compatible:
https://lore.kernel.org/r/20250519080453.29858-2-krzysztof.kozlowski@linaro.org/T/#u

Dependencies were merged, so this brings the necessary sound on SM8750
MTP.  I have patches work-in-progress for USB headset, but this have
dependencies and need some cleanup. I will be posting these separately.

Best regards,
Krzysztof

[PATCH v3 2/3] arm64: dts: qcom: sm8750-mtp: Add sound (speakers, headset codec, dmics)

[Krzysztof Kozlowski]

Add device nodes for most of the sound support - WSA883x smart speakers,
WCD9395 audio codec (headset) and sound card - which allows sound
playback via speakers and recording via DMIC microphones.  Changes bring
necessary foundation for headset playback/recording via USB, but that
part is not yet ready.

[PATCH v3 3/3] arm64: dts: qcom: sm8750-qrd: Add sound (speakers, headset codec, dmics)

[Krzysztof Kozlowski]

Add device nodes for most of the sound support - WSA884x smart speakers,
WCD9395 audio codec (headset) and sound card - which allows sound
playback via speakers and recording via AMIC microphones.  Changes bring
necessary foundation for headset playback/recording via USB, but that
part is not yet ready.

I forgot to mention: vdd-px is new and documented in binding change:
https://lore.kernel.org/linux-devicetree/20250526-b4-asoc-wcd9395-vdd-px-v1-5-64d3cb60313b@linaro.org/

No dependencies, but till binding hits mainline this will be flagged by
dtbs_check.
