The Allwinner A23 SoC and later have an embedded audio codec that uses a separate controller to drive its analog part, which is supported in Linux, with a matching Device Tree binding.
Now that we have the DT validation in place, let's convert the device tree bindings for that controller over to a YAML schemas.
