+Device-Tree bindings for ST IRB IP
+
+Required properties:
+	- compatible: Should contain "st,comms-irb".
+	- 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.
+	- rx-mode: can be "infrared" or "uhf". This property specifies the L1
+	  protocol used for receiving remote control signals. rx-mode should
+	  be present iff the rx pins are wired up.
+	- tx-mode: should be "infrared". This property specifies the L1
+	  protocol used for transmitting remote control signals. tx-mode should
+	  be present iff the tx pins are wired up.
+
+Optional properties:
+	- pinctrl-names, pinctrl-0: the pincontrol settings to configure muxing
+	  properly for IRB pins.
+	- clocks : phandle with clock-specifier pair for IRB.
+
+Example node:
+
+	rc: rc@fe518000 {
+		compatible	= "st,comms-irb";
+		reg		= <0xfe518000 0x234>;
+		interrupts	= <0 203 0>;
+		rx-mode		= "infrared";
+	};
