	  Say yes here to build support for BOSCH BMG160 Tri-axis Gyro Sensor

	  driver connected via I2C or SPI. This driver also supports BMI055

	  gyroscope.



	  This driver can also be built as a module.  If so, the module

	  will be called bmg160_i2c.

	  will be called bmg160_i2c or bmg160_spi.
