+Required properties:
+
+  - compatible : should be "invensense,itg3200"
+  - reg : the I2C address of the sensor
+
+Optional properties:
+
+  - interrupt-parent : should be the phandle for the interrupt controller
+  - interrupts : interrupt mapping for GPIO IRQ
+
+Example:
+
+itg3200@68 {
+	compatible = "invensense,itg3200";
+	reg = <0x68>;
+	interrupt-parent = <&gpio2>;
+	interrupts = <29 IRQ_TYPE_EDGE_RISING>;
