+* Amlogic Meson IR remote control receiver
+
+Required properties:
+ - compatible   : should be "amlogic,meson6-ir"
+ - reg          : physical base address and length of the device registers
+ - interrupts   : a single specifier for the interrupt from the device
+
+Example:
+
+        ir-receiver@c8100480 {
+                compatible= "amlogic,meson6-ir";
+                reg = <0xc8100480 0x20>;
+                interrupts = <0 15 1>;
+        };
