+* InvenSense ITG3200 3-axis gyroscope
+
+Required properties:
+
+ - compatible : "invensense,itg3200"
+ - reg : I2C address, typically 0x68
+
+Optional properties:
+
+ - interrupt-parent : should be the phandle for the interrupt controller
+ - interrupts : interrupt mapping for IRQ
+
+Example:
+
+itg3200@68 {
+ compatible = "invensense,itg3200";
+ reg = <0x68>;
+ interrupt-parent = <&gpio2>;
+ interrupts = <24 IRQ_TYPE_EDGE_RISING>;
+};
