Required properties:

6
 - compatible : should be one of

7
		"invensense,mpu6000"

8
		"invensense,mpu6050"

9
 		"invensense,mpu6500"

10
		"invensense,mpu6515"

11
		"invensense,mpu9150"

12
		"invensense,mpu9250"

13
		"invensense,mpu9255"

14
		"invensense,icm20608"

15
		"invensense,icm20609"

16
		"invensense,icm20689"

17
		"invensense,icm20602"

18
		"invensense,icm20690"

19
		"invensense,iam20680"

20
 - reg : the I2C address of the sensor

21
 - interrupts: interrupt mapping for IRQ. It should be configured with flags

22
   IRQ_TYPE_LEVEL_HIGH, IRQ_TYPE_EDGE_RISING, IRQ_TYPE_LEVEL_LOW or

23
   IRQ_TYPE_EDGE_FALLING.

24


25
  Refer to interrupt-controller/interrupts.txt for generic interrupt client node

26
  bindings.

28
Optional properties:

29
 - vdd-supply: regulator phandle for VDD supply

30
 - vddio-supply: regulator phandle for VDDIO supply

31
 - mount-matrix: an optional 3x3 mounting rotation matrix

32
 - i2c-gate node.  These devices also support an auxiliary i2c bus.  This is

33
   simple enough to be described using the i2c-gate binding. See

34
   i2c/i2c-gate.txt for more details.

Example:

37
	mpu6050@68 {

38
		compatible = "invensense,mpu6050";

39
		reg = <0x68>;

40
		interrupt-parent = <&gpio1>;

41
		interrupts = <18 IRQ_TYPE_EDGE_RISING>;

42
		mount-matrix = "-0.984807753012208",  /* x0 */

43
		               "0",                   /* y0 */

44
		               "-0.173648177666930",  /* z0 */

45
		               "0",                   /* x1 */

46
		               "-1",                  /* y1 */

47
		               "0",                   /* z1 */

48
		               "-0.173648177666930",  /* x2 */

49
		               "0",                   /* y2 */

50
		               "0.984807753012208";   /* z2 */

	};
