The LSM9DS1's accelerometer / gyroscope unit and it's magnetometer (separately supported in iio/magnetometer/st_magn*) are located on a separate i2c addresses on the bus. For the datasheet, see https://www.st.com/resource/en/datasheet/lsm9ds1.pdf Treat it just like the LSM6* devices and, despite it's name, hook it up to the st_lsm6dsx driver, using it's basic functionality. accelerometer and gyroscope are not independently clocked. It runs at the gyro frequencies if both are enabled, see chapter 7.12 of the datasheet. We could have handled this as a single IIO device but we have split it up to be more consistent with the other more flexible devices. Despite supporting and testing the LSM9DS1, we call the gyro channels iio_chan_spec struct "st_lsm6ds0_gyro_channels" because the register description is equal. This suggests that supporting LSM6DS0 should be trivial to do. Signed-off-by: Martin Kepplinger <martin.kepplinger@puri.sm> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
