The ROHM KX134-1211 has very similar register interface as KX132-1211
does. The main differencies are the content of the "Who am I"
identification register and different g-ranges. The KX132-1211 can
measure ranges from +/- 2g to +/-16g where the KX134-1211 supports
measuring ranges +/- 8g to +/- 64g.

Support the ROHM KX134-1211.
