Subject: [PATCH v3 0/2] Add ADXL367 driver

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
