Add an:

additionalProperties: false

With that,

I did not put that on purpose.
Most of the amlogic devices use an generic ASoC property called
"sound-name-prefix"

You may see examples of that in
arch/arm64/boot/dts/amlogic/meson-axg.dtsi.

That property is not expressed in json schema yet, and I don't
really know what is the best way to add that.

Adding 'additionalProperties: false' right now would generate a fair
amount of warning with 'make dtbs_check'

Just assume it is (and I believe there's a patch I reviewed adding
it). Regardless, you still need to define what the strings are.

That's a good way to have a todo...
