-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>
-- 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 >;
-
-		#size-cells = <0>;
-		#address-cells = <1>;
-	};
