When I do dt_binding_check, below warning is reported: Documentation/devicetree/bindings/sound/renesas,rsnd.example.dt.yaml: \ sound@ec500000: 'dais' is a required property
I looked at all the dts files in the "arch/arm64/boot/dts/renesas/" directory, I found that all nodes that contain the "dais" property have compatible string: "audio-graph-card". So I can be sure that the "$ref: audio-graph.yaml#" should be corrected to "$ref: audio-graph-card.yaml#".
In addition, not all nodes have compatible string "audio-graph-card", so the "$ref: audio-graph-card.yaml#" should be described as "anyOf". To ensure the validation of "anyOf" always passes, group it with the "if" statement, because the result of the "if" statement is always not empty.
'anyOf' is probably not right here.
Oh, yes, I think I should use "if" statement to enumerate cases where "audio-graph-card.yaml" is required.
In any case, the is going to conflict with my series[1].
OK, I'll rework my patch based on your series.
