V2 -> V3
 * limit number of fifo entries read to multiple of set size to avoid
   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
