Also, the cs-gpio is part of the spi master binding so no need to have it here as we are showing how the actual device binding works.

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.
