The patch set covers the following topics:
- add debug register and regmap cache
- prepare iio channel scan_type and scan_index
- prepare interrupt handling
- implement fifo with watermark
- add activity/inactivity together with auto-sleep with link bit
- documentation
Since activity and inactivity here are implemented covering all axis, I
assumed x&y&z. Thus the driver uses a fake channel for activity/inactiviy.

- verify reorganization of half condition for Activity [v1 09/12] and Inactivity [v1 10/12]
- verify usage of MICRO instead of 1000000

- removal of duplicate blanks in various places (sry, my keyboard died) [v1 07/12]
v1 -> v2:
- usage of units.h
- simplify approach for return values
