   5 Required properties:
   6  - compatible : should be one of
   7                 "invensense,mpu6050"
   8                 "invensense,mpu6500"
   9                 "invensense,mpu6515"
  10                 "invensense,mpu9150"
  11                 "invensense,mpu9250"
  12                 "invensense,mpu9255"
  13                 "invensense,icm20608"
  14                 "invensense,icm20602"
  15  - reg : the I2C address of the sensor
  16  - interrupts: interrupt mapping for IRQ. It should be configured with flags
  17    IRQ_TYPE_LEVEL_HIGH, IRQ_TYPE_EDGE_RISING, IRQ_TYPE_LEVEL_LOW or
  18    IRQ_TYPE_EDGE_FALLING.
  19
  20   Refer to interrupt-controller/interrupts.txt for generic interrupt client node
  21   bindings.
  22
  23 Optional properties:
  24  - vddio-supply: regulator phandle for VDDIO supply
  25  - mount-matrix: an optional 3x3 mounting rotation matrix
  26  - i2c-gate node.  These devices also support an auxiliary i2c bus.  This is
  27    simple enough to be described using the i2c-gate binding. See
  28    i2c/i2c-gate.txt for more details.
