What's the point of this? You have entire commit msg to explain such
weird duplication. Otherwise sorry, don't duplicate unnecessarily.
Devices are compatible, aren't they?

Best regards,

I will drop this, could you please help us to understand what is the correct way to
deal such situation, do we need to update the yaml and add qcs8300 bindings or just
reference to sa8775p bindings in the device tree?

Thanks,
Jingyi

Above diff hunk suggests that devices are compatible, so should be made
compatible in the bindings (use fallback). There are plenty examples of
this for all Qualcomm devices.

The usage of binding seems inconsistent across different Qualcomm drivers. Could you please
confirm that when you mentioned "use fallback", do you mean binding like this?

      - items:
          - enum:
              - qcom,sm8550-sndcard
              - qcom,sm8650-sndcard
          - const: qcom,sm8450-sndcard
