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>

description: |
|
|
The Audio Demultiplexer (ADX) block takes an input stream with up to
|
|
16 channels and demultiplexes it into four output streams of up to 16
|
|
channels each. A byte RAM helps to form output frames by any combination
|
|
of bytes from the input frame. Its design is identical to that of byte
|
|
RAM in the AMX except that the data flow direction is reversed.

ADX has one input and four outputs. Accordingly ACIF (Audio Client
|
|
Interface) port nodes are defined to represent ADX input (port 0)
|
|
and outputs (ports 1 to 4). These are connected to corresponding
|
|
ports on AHUB (Audio Hub).
