iio: imu: inv_icm42600: Fix temperature calculation

2025-06-27T10:13:10Z

commit e2f820014239df9360064079ae93f838ff3b7f8c upstream. >From the documentation: "offset to be added to [Y]_raw prior toscaling by [Y]_scale" Offset should be applied before multiplying scale, so divide offset by scale to make this correct.

iio: imu: st_lsm6dsx: Fix wakeup source leaks on device unbind

iio: imu: bmi270: fix initial sampling frequency configuration

2025-04-07T18:32:48Z

In the bmi270_configure_imu() function, the accelerometer and gyroscope configuration registers are incorrectly written with the mask BMI270_PWR_CONF_ADV_PWR_SAVE_MSK, which is unrelated to these registers. As a result, the accelerometer's sampling frequency is set to 200 Hz instead of the intended 100 Hz. Remove the mask to ensure the correct bits are set in the configuration registers.

iio: imu: bmi270: add support for data ready interrupt trigger

2025-03-04T13:17:51Z

The BMI270 sensor provides two interrupt pins that can be used for different interrupt sources, including a data ready signal. Add support for configuring one the pins as a trigger source. The interrupt pin can be configured with various options: active high or low, push-pull or open-drain, and latched or non-latched.
