Now the question what does "xx" stand for? I cannot find such product on
awinic website:

Why there is no sound-dai-cells?

unevaluatedProperties: false

unless this is not a codec and sound-dai-cells cannot be used?

Does not look like you tested the bindings. Please run `make
dt_binding_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).
