We have added an optional boolean property for configuring a BMI160 interrupt pin as open-drain, as opposed to the default push-pull, so document this. Signed-off-by: Martin Kelly <martin@martingkelly.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

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";
|
|
};
