Changes since v5: 1. Used get_unaligned_be24() and get_unaligned_be16() to parse acceleration and temperature data. This solves sparse errors and also make the code more understandable. Changes since v4: 1. Fix errors reported by sparse. Changes since v3: 1. Fix errors in yaml DT doc. 2. Change SPDX-License-Identifier to GPL-2.0-only OR BSD-2-Clause Changes since v2: 1. Add separate DT binding doc in yaml. 2. Use ____cacheline_aligned buffer for regmap_bulk_read/write calls. 3. Make code consistent by using same style in switch case. 4. Use FIELD_PREP in place of custom macros. 5. Make Kconfig description more informative. Changes since v1: 1. Remove the declarations for static regmap structures from adxl355.h. This was missed in the v1 and caused errors. 2. Make switch case statements consistent by directly returning from each case rather than saving the return in a variable. 3. Some coding style changes. Changes since v0: 1. Move adxl355_hpf_3db_table to adxl355_data structure. This is done to make sure that each device gets its own table. 2. Make local regmap definitions private to adxl355_core.c. 3. Other minor coding style changes.
