Freescale i.MX audio complex with S/PDIF transceiver

Required properties:

  - compatible		: "fsl,imx-audio-spdif"

  - model		: The user-visible name of this sound complex

  - spdif-controller	: The phandle of the i.MX S/PDIF controller


Optional properties:

  - spdif-out		: This is a boolean property. If present, the
			  transmitting function of S/PDIF will be enabled,
			  indicating there's a physical S/PDIF out connector
			  or jack on the board or it's connecting to some
			  other IP block, such as an HDMI encoder or
			  display-controller.

  - spdif-in		: This is a boolean property. If present, the receiving
			  function of S/PDIF will be enabled, indicating there
			  is a physical S/PDIF in connector/jack on the board.

* Note: At least one of these two properties should be set in the DT binding.


Example:

sound-spdif {
	compatible = "fsl,imx-audio-spdif";
	model = "imx-spdif";
	spdif-controller = <&spdif>;
	spdif-out;
	spdif-in;
};
