You can drop '^.*'.

Thanks Rob for review,

cells?

How is this optional?

This needs to be false and fix whatever is missing.

This doesn't match what you have in the schema at all.

+ compatible = "qcom,q6apm-dai";
+ #sound-dai-cels = <1>;
+ };
+
+ q6apm-bedai {
+ compatible = "qcom,q6apm-bedai";
