InvenSense MPU-6050 Six-Axis (Gyro + Accelerometer) MEMS MotionTracking Device

http://www.invensense.com/mems/gyro/mpu6050.html

Required properties:
 - compatible : should be one of
		"invensense,mpu6000"
		"invensense,mpu6050"
 		"invensense,mpu6500"
		"invensense,mpu6515"
		"invensense,mpu9150"
		"invensense,mpu9250"
		"invensense,mpu9255"
		"invensense,icm20608"
		"invensense,icm20609"
		"invensense,icm20689"
		"invensense,icm20602"
		"invensense,icm20690"
		"invensense,iam20680"
 - reg : the I2C address of the sensor
 - interrupts: interrupt mapping for IRQ. It should be configured with flags
   IRQ_TYPE_LEVEL_HIGH, IRQ_TYPE_EDGE_RISING, IRQ_TYPE_LEVEL_LOW or
   IRQ_TYPE_EDGE_FALLING.

Refer to interrupt-controller/interrupts.txt for generic interrupt client node
  bindings.

Optional properties:
 - vdd-supply: regulator phandle for VDD supply
 - vddio-supply: regulator phandle for VDDIO supply
 - mount-matrix: an optional 3x3 mounting rotation matrix
 - i2c-gate node.  These devices also support an auxiliary i2c bus.  This is
   simple enough to be described using the i2c-gate binding. See
   i2c/i2c-gate.txt for more details.

Example:
	mpu6050@68 {
		compatible = "invensense,mpu6050";
		reg = <0x68>;
		interrupt-parent = <&gpio1>;
		interrupts = <18 IRQ_TYPE_EDGE_RISING>;
		mount-matrix = "-0.984807753012208",  /* x0 */
		               "0",                   /* y0 */
		               "-0.173648177666930",  /* z0 */
		               "0",                   /* x1 */
		               "-1",                  /* y1 */
		               "0",                   /* z1 */
		               "-0.173648177666930",  /* x2 */
		               "0",                   /* y2 */
		               "0.984807753012208";   /* z2 */
	};

mpu9250@68 {
		compatible = "invensense,mpu9250";
		reg = <0x68>;
		interrupt-parent = <&gpio3>;
		interrupts = <21 IRQ_TYPE_LEVEL_HIGH>;
		i2c-gate {
			#address-cells = <1>;
			#size-cells = <0>;
			ax8975@c {
				compatible = "ak,ak8975";
				reg = <0x0c>;
			};
		};
	};
