fe2fe330e0 iio:accel:adxl355: Move exports into IIO_ADXL355 namespace 
To avoid unnecessary pollution of the global symbol namespace move the
driver core exports into their own namespace and import that into the two
bus modules.

327a0eaf19 iio: accel: adxl355: Add triggered buffer support 
Provide a way for continuous data capture by setting up buffer support. The
data ready signal exposed at the DRDY pin of the ADXL355 is exploited as
a hardware interrupt which triggers to fill the buffer.
