[PATCH v1 00/12] iio: accel: adxl313: add power-save on activity/inactivity

[Lothar Rubusch <l.rubusch@gmail.com>]

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

Similar situation and approach as for the ADXL345. AC/DC coupling might be
a pending option as it is quite the same as for ADXL345.

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.
