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.
