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

 - interrupt-names : set to "INT1" if INT1 pin should be used as interrupt

   input, set to "INT2" if INT2 pin should be used instead

 - drive-open-drain : set if the specified interrupt pin should be configured as

   open drain. If not set, defaults to push-pull.

Examples:

bmi160@68 {

	compatible = "bosch,bmi160";

	reg = <0x68>;

	interrupt-parent = <&gpio4>;

	interrupts = <12 IRQ_TYPE_EDGE_RISING>;

	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";

};
