uac1 and uac2 functions are available through the configfs interface
and it should be possible to build them without building their legacy
gadgets.

	  This Audio function is compatible with USB Audio Class

	  specification 2.0. It implements 1 AudioControl interface,

	  1 AudioStreaming Interface each for USB-OUT and USB-IN.

	  This driver doesn't expect any real Audio codec to be present

	  on the device - the audio streams are simply sinked to and

	  sourced from a virtual ALSA sound card created. The user-space

	  application may choose to do whatever it wants with the data

	  received from the USB Host and choose to provide whatever it

	  wants as audio data to the USB Host.
