+PixArt Imaging PAT9125 Optical Tracking Miniature Chip device driver
+
+Required properties:
+	- compatible: must be "pixart,pat9125"
+	- 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>;
+};
