[alsa-devel] [PATCH 2/5] dt-bindings: sound: Convert Allwinner A10 codec to a schema

From: Maxime Ripard <maxime.ripard at bootlin.com>
The Allwinner SoCs have an embedded audio codec that 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.

- Documentation/devicetree/bindings/dma/dma.txt
-- dma-names: should include "tx" and "rx".
-- clocks: a list of phandle + clock-specifer pairs, one for each entry
- in clock-names.
-- clock-names: should contain the following:
- - "apb": the parent APB clock for this controller
- - "codec": the parent module clock
