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
Documentation/devicetree/bindings/sound/qcom,sc7180.example.dts:43.24-52.15: Warning (unit_address_vs_reg): /example-0/sound/dai-link@1: 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.

Please don't use 'definitions'. Either just duplicate it or you can do 
'patternProperties'.

This is a common property. You can assume we have a common schema 
definition for it. IOW, 'sound-dai: true' is enough as it's always a 
single phandle+args.

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!

In the examples I found,
Documentation/devicetree/bindings/sound/amlogic,gx-sound-card.yaml,
Documentation/devicetree/bindings/sound/samsung,midas-audio.yaml
use:

      sound-dai:
        $ref: /schemas/types.yaml#/definitions/phandle
        description: phandle of the CPU DAI

Documentation/devicetree/bindings/sound/simple-card.yaml
just use

      sound-dai:
        maxItems: 1

In v4, I used 'sound-dai: true' as suggested.

But I am a bit confused about assuming there is a common schema
definition for it.
I checked the code at https://github.com/devicetree-org/dt-schema but
did not found the definition for it.
Did I miss something here ?

Thanks for the help!
