Yes, from IIO point of view, should increase driver features in future
to integrate buffer, scan mode, triggers...
Or perhaps i will need to introduce some of these concepts to handle
ASoC requirement in IIO...

FYI, DFSDM also offers some features like Analog watchdog, short circuit
and SPI/manchester bus clock absence detection detection...:)
