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.
