This patch adds YAML schema for DT bindings of few AHUB modules. These devices will be registered as ASoC components and bindings will be used on Tegra210 and later chips. The bindings for below mentioned modules are added: * SFC (Sampling Frequency Converter) * MVC (Master Volume Control) * AMX (Audio Multiplexer) * ADX (Audio Demultiplexer) * Mixer Signed-off-by: Sameer Pujar <spujar@nvidia.com> Cc: Rob Herring <robh+dt@kernel.org> Reviewed-by: Rob Herring <robh@kernel.org> Link: https://lore.kernel.org/r/1631551342-25469-5-git-send-email-spujar@nvidia.com Signed-off-by: Mark Brown <broonie@kernel.org>

The Sampling Frequency Converter (SFC) converts the sampling frequency
|
|
of the input signal from one frequency to another. It supports sampling
|
|
frequency conversions of streams of up to two channels (stereo).
