+Freescale Synchronous Audio Interface (SAI).
+
+The SAI is based on I2S module that used communicating with audio codecs,
+which provides a synchronous audio interface that supports fullduplex
+serial interfaces with frame synchronization such as I2S, AC97, TDM, and
+codec/DSP interfaces.
+
+
+Required properties:
+- compatible: Compatible list, contains "fsl,vf610-sai".
+- reg: Offset and length of the register set for the device.
+- clocks: Must contain an entry for each entry in clock-names.
+- clock-names : Must include the "sai" entry.
+- dmas : Generic dma devicetree binding as described in
+ Documentation/devicetree/bindings/dma/dma.txt.
+- dma-names : Two dmas have to be defined, "tx" and "rx".
+- pinctrl-names: Must contain a "default" entry.
+- pinctrl-NNN: One property must exist for each entry in pinctrl-names.
+ See ../pinctrl/pinctrl-bindings.txt for details of the property values.
+
+Example:
+sai2: sai@...31000 {
+ compatible = "fsl,vf610-sai";
+ reg = <0x40031000 0x1000>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_sai2_1>;
+ clocks = <&clks VF610_CLK_SAI2>;
+ clock-names = "sai";
+ dma-names = "tx", "rx";
+ dmas = <&edma0 0 VF610_EDMA_MUXID0_SAI2_TX>,
+ <&edma0 0 VF610_EDMA_MUXID0_SAI2_RX>;
+};
