Subject: [PATCH 0/6] Enable USB audio offloading on Fairphone 4 smartphone

Since the series for the USB sound offloading driver was finally merged,
we can add the sm6350 dts and enable it on Fairphone 4.

A few devicetree binding bits have also been missing in that series, so
there's some extra patches for the basics in this series.

Depends on:
- For qcom,sm8250.yaml & sm8250.c:
  https://lore.kernel.org/linux-arm-msm/20250425-fp5-dp-sound-v3-0-7cb45180091b@fairphone.com/T/
- For dts:
  https://lore.kernel.org/linux-arm-msm/20250321-sm6350-apr-v1-1-7805ce7b4dcf@fairphone.com/

Devicetree patches go through qcom
