   4
   5 Required properties:
   6  - compatible : should be one of
   7                 "invensense,mpu6050"
   8                 "invensense,mpu6500"
   9                 "invensense,mpu9150"
  10                 "invensense,mpu9250"
  11                 "invensense,icm20608"
  12  - reg : the I2C address of the sensor
  13  - interrupt-parent : should be the phandle for the interrupt controller
  14  - interrupts : interrupt mapping for GPIO IRQ
  15
  16 Optional properties:
  17  - mount-matrix: an optional 3x3 mounting rotation matrix
  18  - i2c-gate node.  These devices also support an auxiliary i2c bus.  This is
  19    simple enough to be described using the i2c-gate binding. See
  20    i2c/i2c-gate.txt for more details.
