[PATCH v3 0/9] iio: ad3552r-hs: add support for ad3541/42r Angelo Dureghello

[Angelo Dureghello]

This patchset add support for ad3541/42r, 16MUPS, respectively
single and dual channel DACs, together with some minor fixes.

The ad354xr connect through a DSPI bus (while ad355xr through
QSPI), so a new fpga HDL supporting bus mode switch has been
developed to support them.
