+Device-Tree bindings for hix5hd2 ir IP
+
+Required properties:
+       - compatible: Should contain "hisilicon,hix5hd2-ir".
+       - reg: Base physical address of the controller and length of memory
+         mapped region.
+       - interrupts: interrupt-specifier for the sole interrupt generated by
+         the device. The interrupt specifier format depends on the interrupt
+         controller parent.
+       - clocks: clock phandle and specifier pair.
+       - hisilicon,power-syscon: phandle of syscon used to control power.
+
+Optional properties:
+       - linux,rc-map-name : Remote control map name.
+
+Example node:
+
+       ir: ir@f8001000 {
+               compatible = "hisilicon,hix5hd2-ir";
+               reg = <0xf8001000 0x1000>;
+               interrupts = <0 47 4>;
+               clocks = <&clock HIX5HD2_FIXED_24M>;
+               hisilicon,power-syscon = <&sysctrl>;
+               linux,rc-map-name = "rc-tivo";
+       };
