+Device tree bindings for IR LED connected through SPI bus which is used as
+remote controller.
+
+The IR LED switch is connected to the MOSI line of the SPI device and the data
+are delivered thourgh that.
+
+Required properties:
+	- compatible: should be "ir-spi".
+
+Optional properties:
+	- irled,switch: specifies the gpio switch which enables the irled/
+	- negated: boolean value that specifies whether the output is negated
+	  with a NOT gate.
+	- duty-cycle: 8 bit value that stores the percentage of the duty cycle.
+	  it can be 50, 60, 70, 75, 80 or 90.
+
+Example:
+
+        irled@0 {
+                compatible = "ir-spi";
+                reg = <0x0>;
+                spi-max-frequency = <5000000>;
+                irled,switch = <&gpr3 3 0>;
+		negated;
+		duty-cycle = /bits/ 8 <60>;
+        };
