[v3] iio: accel: adxl313: add power-save on activity/inactivity

[PATCH v3 03/12] iio: accel: adxl313: configure scan type for buffer

Posted by Lothar Rubusch 6 months, 4 weeks ago

According to the datasheet the ADXL313 uses 13 bit in full resolution.
Also, add signedness, storage bits and endianness.
