+Device-Tree bindings for SUNXI IR controller found in sunXi SoC family
+
+Required properties:
+- compatible	    : should be "allwinner,sun7i-a20-ir";
+- clocks	    : list of clock specifiers, corresponding to
+		      entries in clock-names property;
+- clock-names	    : should contain "apb0_ir0" and "ir0" entries;
+- interrupts	    : should contain IR IRQ number;
+- reg		    : should contain IO map address for IR.
+
+Optional properties:
+- linux,rc-map-name : Remote control map name.
+
+Example:
+
+ir0: ir at 01c21800 {
+       	compatible = "allwinner,sun7i-a20-ir";
+       	clocks = <&apb0_gates 6>, <&ir0_clk>;
+       	clock-names = "apb0_ir0", "ir0";
