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.

The Output Processing Engine (OPE) is one of the AHUB client. It has PEQ (Parametric Equalizer) and MBDRC (Multi Band Dynamic Range Compressor) sub blocks for data processing. The PEQ block gets samples from the MBDRC block.

This patch registers OPE driver with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes OPE interfaces, which can be used to connect different components in the ASoC layer. Makefile and Kconfig support is added to allow build the driver.
