-Device-Tree bindings for Xilinx I2S PL block
-
-The IP supports I2S based playback/capture audio
-
-Required property:
- - compatible: "xlnx,i2s-transmitter-1.0" for playback and
-	       "xlnx,i2s-receiver-1.0" for capture
-
-Required property common to both I2S playback and capture:
- - reg: Base address and size of the IP core instance.
- - xlnx,dwidth: sample data width. Can be any of 16, 24.
- - xlnx,num-channels: Number of I2S streams. Can be any of 1, 2, 3, 4.
-		      supported channels = 2 * xlnx,num-channels
-
-Example:
-
-	i2s_receiver@...80000 {
-		compatible = "xlnx,i2s-receiver-1.0";
-		reg = <0x0 0xa0080000 0x0 0x10000>;
-		xlnx,dwidth = <0x18>;
-		xlnx,num-channels = <1>;
-	};
-	i2s_transmitter@...90000 {
-		compatible = "xlnx,i2s-transmitter-1.0";
-		reg = <0x0 0xa0090000 0x0 0x10000>;
-		xlnx,dwidth = <0x18>;
-		xlnx,num-channels = <1>;
-	};
