Something generic as a fallback for the driver to binding against I would be fine with, but not something that avoids people documenting their devices. Also, I think "backend" should be dropped from the filename/title/descriptions, the ads1201 is "just" an delta-sigma modulator.:wq > + - ads1201 Missing vendor prefix.
