The Master Volume Control (MVC) provides gain or attenuation to a digital signal path. It can be used in input or output signal path for per-stream volume control or it can be used as master volume control. The MVC block has one input and one output. The input digital stream can be mono or multi-channel (up to 7.1 channels) stream. An independent mute control is also included in the MVC block. This patch registers MVC driver with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes MVC interfaces, which can be used to connect different components in the ASoC layer. Makefile and Kconfig support is added to allow build the driver. It can be enabled in the DT via "nvidia,tegra210-mvc" compatible binding.
