[PATCH v2 1/6] ASoC: tegra: Add binding doc for OPE module

Fri May 27 12:26:07 CEST 2022
This patch adds YAML schema for DT bindings of Output Processing
Engine (OPE) module. It consists of Parametric Equalizer (PEQ)
and Multi Band Dynamic Range Compressor (MBDRC) sub blocks and
binding doc for these blocks are added as well. The OPE will be
registered as an ASoC component and can be plugged into an audio
path as per need via ALSA mixer controls. The DT bindings are
applicable on Tegra210 and later SoCs where OPE module is present.

+description:
+ The Multi Band Dynamic Range Compressor (MBDRC) is part of Output
+ Processing Engine (OPE) which interfaces with Audio Hub (AHUB) via
+ Audio Client Interface (ACIF). MBDRC can be used as a traditional
+ single full band or a dual band or a multi band dynamic processor.

+description:
+ The Parametric Equalizer (PEQ) is a cascade of biquad filters with
+ each filter tuned based on certain parameters. It can be used to
+ equalize the irregularities in the speaker frequency response.
+ PEQ sits inside Output Processing Engine (OPE) which interfaces
+ with Audio Hub (AHUB) via Audio Client Interface (ACIF).
