+ADI AXI-I2S controller
+
+Required properties:
+ - compatible : Must be "adi,axi-i2s-1.00.a"
+ - reg : Must contain I2S core's registers location and length
+ - clocks : Pairs of phandle and specifier referencing the controller's clocks.
+   The controller expects two clocks, the clock used for the AXI interface and
+   the clock used as the sampling rate reference clock sample.
+ - clock-names : "axi" for the clock to the AXI interface, "ref" 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 two dma channels, one for transmit and one for
+   receive.
+ - dma-names : "tx" for the transmit channel, "rx" for the receive channel.
+
+For more details on the 'dma', 'dma-names', 'clock' and 'clock-names' properties
+please check:

+Example:
+
+        i2s: i2s@0x77600000 {
+                compatible = "adi,axi-i2s-1.00.a";
+                reg = <0x77600000 0x1000>;
+                clocks = <&clk 15>, <&audio_clock>;
+                clock-names = "axi", "ref";
+                dmas = <&ps7_dma 0>, <&ps7_dma 1>;
+                dma-names = "tx", "rx";
+        };
