My bot found errors running 'make dt_binding_check' on your patch:

Documentation/devicetree/bindings/sound/qcom,sc7180.example.dts:32.24-41.15: Warning (unit_address_vs_reg): /example-0/sound/dai-link@0: node has a unit name, but no reg or ranges property

See https://patchwork.ozlabs.org/patch/1339316

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure dt-schema is up to date:

pip3 install git+https://github.com/devicetree-org/dt-schema.git@master --upgrade

Please check and re-submit.

I have passed this in v2 patch, but removed reg in v3 patch since it
is not used.
In v4, I have added back reg = <0> and reg = <1> into the example, and
reg property into schema to fix this error.
Since reg property is not used in the driver, I am not sure whether I
should add it in the schema.
Please let me know which is preferred. Thanks!
