-Device-Tree bindings for GPIO IR receiver
-
-Required properties:
-	- compatible: should be "gpio-ir-receiver".
-	- gpios: specifies GPIO used for IR signal reception.
-
-Optional properties:
-	- linux,rc-map-name: see rc.txt file in the same
-	  directory.
-	- linux,autosuspend-period: autosuspend delay time,
-	  the unit is milisecond.
-
-Example node:
-
-	ir: ir-receiver {
-		compatible = "gpio-ir-receiver";
-		gpios = <&gpio0 19 1>;
-		linux,rc-map-name = "rc-rc6-mce";
-		linux,autosuspend-period = <125>;
-	};
