KX022A is a 3-axis Accelerometer from ROHM/Kionix. The sensor features include variable ODRs, I2C and SPI control, FIFO/LIFO with watermark IRQ, tap/motion detection, wake-up & back-to-sleep events, four acceleration ranges (2, 4, 8 and 16g) and probably some other cool features. Add the basic device tree description for the accelerometer. Only basic accelerometer features are considered as of now - new properties may or may not be needed in the future when rest of the features are supported.

KX022A is a 3-axis accelerometer supporting +/- 2G, 4G, 8G and 16G ranges,
|
|
output data-rates from 0.78Hz to 1600Hz and a hardware-fifo buffering.
|
|
KX022A can be accessed either via I2C or SPI.
