Subject: [PATCH v3 0/2] iio: add driver for Bosch BMA400 accelerometer

This patchset adds a IIO driver for the Bosch BMA400 3-axes ultra low-power
accelerometer. The initial implementation of the driver adds read support for
the acceleration and temperature data registers. The driver also has support
for reading and writing to the output data rate, oversampling ratio, and scale
configuration registers.

I've ran some basic tests with libiio and I've run the device tree checks. Are
there other tests that are recommended to be run for a new device?

Thanks again for the reviews!

Cheers,

 - Dan
