data unalignment

The ADXL367 is an ultralow power, 3-axis MEMS accelerometer.
The ADXL367 does not alias input signals to achieve ultralow power
consumption, it samples the full bandwidth of the sensor at all
data rates. Measurement ranges of +-2g, +-4g, and +-8g are available,
with a resolution of 0.25mg/LSB on the +-2 g range.
In addition to its ultralow power consumption, the ADXL367
has many features to enable true system level power reduction.
It includes a deep multimode output FIFO, a built-in micropower
temperature sensor, and an internal ADC for synchronous conversion
of an additional analog input.
V1 -> V2
* add support for vdd and vddio supplies
* lock fifo_watermark retrieval
* fix indentation of sysfs_emit for fifo_mode
* dt-bindings: add spi-max-frequency: true
* dt-bindings: remove cs-gpios property
* dt-bindings: remove status property
* dt-bindings: add support for vdd
V2 -> V3
* MAINTAINERS: use wildcard for adxl367
* dt-bindings: adxl367@addr -> accelerometer@addr
* put asm include after linux includes
* drop registers accessed implicitly
* fifo_full -> fifo_watermark
* print expected device id
* remove INDIO_BUFFER_HARDWARE
* inline ADXL367_EVENT macro
* inline ADXL367_14BIT_SCAN_INFO
* inline regulator enum
* remove of.h in spi driver
* cast const void * to const u8 * in spi read
* switch to trigger-less buffer
* increase reset time as advised by hardware team
* let iio framework validate available channel masks
* enable adc or temp channel automatically on single read
* wait for 100ms after enabling adc or temp for output
to settle on single read (waiting on hardware team input)
* enable adc or temp channel automatically on buffered read
* claim direct mode when setting range
* claim direct mode when setting odr
* claim direct mode when setting event config
* sort status masks in descending bit order
* hardcode indio_dev name
* add some comments regarding spi message layout
* use bulk_write for activity and inactivity threshold
* use bulk_write for inactivity time
* use bool as return type of fifo format finding function
* remove shift from channels scan type
