+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>;

Unless it is very recent, I don't the the invensense vendor-prefix is in
vendor-prefixes.txt. Please add that to the patch.

Otherwise, there is nothing here that isn't covered by the trivial
i2c bindings - thus perhaps it should be an entry in bindings/i2c/trivial-devices.txt?

Personally I'm not that fond of the trivial file as a single location
for the relevant info makes more sense to me. Still thought I'd bring
it up as a possibility.

V2:
Added entries to i2c/trivial-devices and also add invensense to vendor-prefixes file.
