+
+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>
+- clocks: Input clock specifier. Refer to common clock bindings.
+
+Optional properties:
+- Child nodes conforming to i2c bus binding
+- clock-names: Input clock name, should be 'pclk'.
+
+Example:
+
+	axi_iic_0: i2c@40800000 {
+		compatible = "xlnx,xps-iic-2.00.a";
+		clocks = <&clkc 15>;
+		interrupts = < 1 2 >;
+		reg = < 0x40800000 0x10000 >;
