+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";
+       };
