+Device-Tree bindings for SUNXI IR controller found in sunXi SoC family
+
+Required properties:
+- compatible       : should be "allwinner,sun4i-a10-ir";
+- clocks           : list of clock specifiers, corresponding to
+                     entries in clock-names property;
+- clock-names      : should contain "apb" and "ir" 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@01c21800 {
+       compatible = "allwinner,sun4i-a10-ir";
+       clocks = <&apb0_gates 6>, <&ir0_clk>;
+       clock-names = "apb", "ir";
+       interrupts = <0 5 1>;
+       reg = <0x01C21800 0x40>;
+       linux,rc-map-name = "rc-rc6-mce";
+};
