+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:
+ * resource-names.txt
+ * clock/clock-bindings.txt
+ * dma/dma.txt

+Example:
+
+ i2s: i2s@0x77600000 {

+ reg = <0x77600000 0x1000>;
