2019-12-29iio: accel: Add driver for the BMA400Dan Robertson
Add a IIO driver for the Bosch BMA400 3-axes ultra-low power accelerometer. The driver supports reading from the acceleration and temperature registers. The driver also supports reading and configuring the output data rate, oversampling ratio, and scale.
