As the group names below have a suffix ("_chselX"), I think it would be
good to have a suffix in this group name, too.
Usually we have splits like "data" and "ctrl", but in this case, the group
covers both data and control signals.
"adi_common"? "adi_base"? "adi_spi" (but it's only SPI in mode 2/3)?

I'm out of inspiration...

when I'm talking to journalists I just say "programmer" or something like that.
