Bosch BMI160 - Inertial Measurement Unit with Accelerometer, Gyroscope
and externally connectable Magnetometer

https://www.bosch-sensortec.com/bst/products/all_products/bmi160

Required properties:
 - compatible : should be "bosch,bmi160"
 - reg : the I2C address or SPI chip select number of the sensor
 - spi-max-frequency : set maximum clock frequency (only for SPI)

Optional properties:
 - interrupts : interrupt mapping for IRQ, must be IRQ_TYPE_LEVEL_LOW
 - interrupt-names : set to "INT1" if INT1 pin should be used as interrupt
   input, set to "INT2" if INT2 pin should be used instead

Examples:

bmi160@68 {
	compatible = "bosch,bmi160";
	reg = <0x68>;

	interrupt-parent = <&gpio4>;
	interrupts = <12 IRQ_TYPE_LEVEL_LOW>;
	interrupt-names = "INT1";
};

bmi160@0 {
	compatible = "bosch,bmi160";
	reg = <0>;
	spi-max-frequency = <10000000>;

	interrupt-parent = <&gpio2>;
	interrupts = <12 IRQ_TYPE_LEVEL_LOW>;
	interrupt-names = "INT2";
};
