-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";
-};
