[PATCH v2 0/4] iio: accel: adxl372: add ADXL371 support

[Antoniu Miclaus <antoniu.miclaus@analog.com>]

Add support for the Analog Devices ADXL371, a +-200g 3-axis MEMS
accelerometer that shares the same register map as the ADXL372 but
differs in ODR/bandwidth values (320-5120 Hz vs 400-6400 Hz) and
timer scale factors.

The first patch introduces a chip_info structure to parameterize
device-specific properties, replacing hardcoded values with per-chip
lookups. The second patch adds the ADXL371 compatible string to the
dt-binding. The third patch factors out the buffer and trigger setup
into a dedicated helper to reduce probe complexity. The fourth patch
adds the ADXL371 chip_info and disables FIFO support due to a silicon
anomaly (er001) that causes FIFO data misalignment on all current
ADXL371 silicon.

Changes in v2:
 - Switch from custom sysfs callbacks to read_avail() with
   info_mask_shared_by_type_available for sampling_frequency and
   filter_low_pass_3db_frequency available attributes.
 - Add new patch (3/4) factoring out buffer and trigger setup from
   probe into adxl372_buffer_setup() helper.
 - Use designated initializers for ADXL371 frequency tables.
 - Add Acked-by from Conor Dooley on dt-bindings patch.
