Subject: [PATCH v4 00/19] iio: accel: bma220 improvements

Series of patches that switch the driver to the regmap API and add
i2c connectivity.

Tested in I2C and SPI modes with two different sensors.

Event-related code was skipped since the patch series was getting too
large.

Bindings have been merged into testing branch, but this series is still
based on 'togreg'.

Contains fixes based on feedback from Krzysztof, David, Jonathan and Andy.
