[PATCH v6 0/7] iio: accel: adxl345: Add spi-3wire feature

[Lothar Rubusch]

Pass a function setup() as pointer from SPI/I2C specific modules to the
core module. Implement setup() to pass the spi-3wire bus option, if
declared in the device-tree.

In the core module, then update data_format register configuration bits
instead of overwriting it. The changes allow to remove a data_range field.
