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;
};

* mvebu (Kirkwood, Dove, Armada 370) audio controller
Required properties:
- compatible: "marvell,mvebu-audio"
- reg: physical base address of the controller and length of memory mapped
region.
- interrupts: list of two irq numbers.
The first irq is used for data flow and the second one is used for errors.
- clocks: one or two phandles.
The first one is mandatory and defines the internal clock.
The second one is optional and defines an external clock.
- clock-names: names associated to the clocks:
"internal" for the internal clock
"extclk" for the external clock
Example:
i2s1: audio-controller@b4000 {
compatible = "marvell,mvebu-audio";
reg = <0xb4000 0x2210>;
interrupts = <21>, <22>;
clocks = <&gate_clk 13>;
clock-names = "internal";
