[PATCH v3 0/4] iio: accel: adxl345: Split driver into core and I2C then add SPI support

[Eva Rachel Retuya]

This patchset modifies the adxl345 to use regmap. In doing so, we can
easily introduce SPI support and let regmap handle the rest.

Recap of basic features: read_raw for x, y and z axes, scale. After
applying this series, driver now supports the SPI protocol and enumeration
of device via device tree.

Changes from v2:
* Drop PATCH 4 iio: accel: adxl345: Add ACPI support
* Add OF match table on both I2C and SPI files and document them

Changes from v1:
iio: accel: adxl345: Use I2C regmap instead of direct I2C access
* Move other deletions from patch 2 in here -- make it clear what got deleted
  and/or modified that is hard to see previously
* Introduce the driver header file "adxl345.h" here instead of doing it in the
  next patch
* Completely omit traces of i2c_client and let this file (adxl345.c) mirror the
  core file on the next patch.
* Improve debugging print about invalid device ID in probe.

* Update Kconfig to Jonathan's preferred style
* Improve similarity index from 78% to 100% (rename detection)
iio: accel: adxl345: Add ACPI support
* Correct acpi_device_id: ADX0345 -> ADS0345
