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.
