The IC being used in those devices is a  bmi323 but as a result of how the ACPI table reports that device, it is detected by the existing kernel module and we have no way of differentiating until after the chip ID probe.

bmc150 driver supports multiple accelerometer sensors such as
bma222, bma280, bmi055 and all of them are having similar
register map, but the bmi323 register map is completely different
from bmc150.
