+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>;
