dt-bindings:iio:imu:invensense,mpu6050: txt to yaml conversion 



As Rob Herring suggested, this no long requires the explicit
i2c-gate binding, but instead just used i2c-controller.yaml
directly.

2 prior examples combinded into one as a single example can show
all of the binding elements as long as the right part is selected.

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>;

			};

		};

	};
