Say yes here to build support for the following Bosch accelerometers:
BMC150, BMI055, BMA250E, BMA222E, BMA255, BMA280.
- Currently this only supports the device via an i2c interface.
-
This is a combo module with both accelerometer and magnetometer.
This driver is only implementing accelerometer part, which has
its own address and register map.
