+Xilinx IIC controller:
+
+Required properties:
+- compatible : Must be "xlnx,xps-iic-2.00.a"
+- reg : IIC register location and length
+- interrupts : IIC controller unterrupt
+- #address-cells = <1>
+- #size-cells = <0>
+
+Optional properties:
+- Child nodes conforming to i2c bus binding
+
+Example:
+
+        axi_iic_0: i2c@40800000 {
+                compatible = "xlnx,xps-iic-2.00.a";
+                interrupts = < 1 2 >;
+                reg = < 0x40800000 0x10000 >;
+
+                #size-cells = <0>;
+                #address-cells = <1>;
+        };
