+Required properties:

+ - reg: i2c address where to find the device
+ - interrupts : the sole interrupt generated by the device
+
+ Refer to interrupt-controller/interrupts.txt for generic
+ interrupt client node bindings.

+Example:
+
+pat9125@75 {
+ compatible = "pixart,pat9125";
+ reg = <0x75>;
+ interrupt-parent = <&gpio3>;
+ interrupts = <12 IRQ_TYPE_EDGE_FALLING>;
