+* 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>;
+       };
