		ADXL362 3-axis SPI accelerometer
		When setting the accelerometer DTS properties and want to use
		streaming funcionality, make sure to include adxl362.h and
		use the macros defined there for fifo-mode and fifo-watermark properties.

		Example:
		#include <zephyr/dt-bindings/sensor/adxl362.h>

		adxl362: adxl362@0 {
		...
		fifo-mode = <ADXL362_FIFO_MODE_STREAM>;
