On the parallel version, the current implementation is only compatible

Doing so required to declare ad7606_chip_info structures in the .h file
so to make them accessible to all the driver files that can set a
pointer to the corresponding chip as the driver data.

Maybe my eyes are tricking me but I'm not seeing any MODULE_IMPORT_NS() in the
drivers?
Hi Nuno,
The ad7606_spi.c and ad7606_par.c use MODULE_IMPORT_NS(IIO_AD7606).
Chip infos are used in the "coupling" structures, e.g:
static const struct ad7606_bus_info ad7616_bus_info = {
.chip_info = &ad7616_info,¬
.bops = &ad7616_spi_bops,¬
};¬
