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/jack on the board or it's connecting to some
    other IP block, such as an HDMI encoder/display-controller.

  - spdif-in : This is a boolean property. If present, the receiving
    function of S/PDIF will be enabled, indicating there's 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;
};
