98496ccdf0 iio: accel: bma400: prevent setting accel scale too low 
This puts an upper bound on "val2" but it also needs to have a lower
bound (BMA400_SCALE_MIN).

465c811f1f iio: accel: Add driver for the BMA400 
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.
