[PATCH v2 04/52] ASoC: dt-bindings: Convert Simple Amplifier binding to a schema

From: Maxime Ripard <hidden>
Date: 2021-09-01 09:19:10
Also in: alsa-devel, linux-devicetree
Subsystem: open firmware and flattened device tree bindings, sound - soc layer / dynamic audio power management (asoc), the rest · Maintainers: Rob Herring, Krzysztof Kozlowski, Conor Dooley, Liam Girdwood, Mark Brown, Linus Torvalds 

Simple audio amplifiers are supported by 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 driver over to a YAML schema.
