What: /sys/bus/iio/devices/iio:deviceX/buffer/length_align_bytes
KernelVersion: 5.4
DMA buffers tend to have a alignment requirement for the
buffers. If this alignment requirement is not met samples might
be dropped from the buffer.
This property reports the alignment requirements in bytes.
This means that the buffer size in bytes needs to be a integer
multiple of the number reported by this file.
The alignment requirements in number of sample sets will depend
on the enabled channels and the bytes per channel. This means
that the alignment requirement in samples sets might change
depending on which and how many channels are enabled. Whereas
the alignment requirement reported in bytes by this property
will remain static and does not depend on which channels are
