-DesignWare I2S controller
-
-Required properties:
- - compatible : Must be "snps,designware-i2s"
- - reg : Must contain the I2S core's registers location and length
- - clocks : Pairs of phandle and specifier referencing the controller's
-   clocks. The controller expects one clock: the clock used as the sampling
-   rate reference clock sample.
- - clock-names : "i2sclk" for the sample rate reference clock.
- - dmas: Pairs of phandle and specifier for the DMA channels that are used by
-   the core. The core expects one or two dma channels: one for transmit and
-   one for receive.
- - dma-names : "tx" for the transmit channel, "rx" for the receive channel.
-
-Optional properties:
- - interrupts: The interrupt line number for the I2S controller. Add this
-   parameter if the I2S controller that you are using does not support DMA.
-
-For more details on the 'dma', 'dma-names', 'clock' and 'clock-names'
-properties please check:

-Example:
-
-	soc_i2s: i2s@7ff90000 {
-		compatible = "snps,designware-i2s";
-		reg = <0x0 0x7ff90000 0x0 0x1000>;
-		clocks = <&scpi_i2sclk 0>;
-		clock-names = "i2sclk";
-		#sound-dai-cells = <0>;
-		dmas = <&dma0 5>;
-		dma-names = "tx";
-	};
