Hi Jonathan,
A number of our ADC drivers use is_visible to hide some channels in certain=
configurations.
Now that the channel registration is done in the core.
How do you think we should do that, from now on?
Greetings,
Michael

Different channel sets for the different devices. It's slightly more static data, but
not too bad. So basically how we did it before that is_visible function came along.
See max1363 or the version of adis16400 I'll push out to the onwards tree shortly.
That's the one big disadvantage I've seen, but I think the gains outweigh the slightly
larger amount of code in those places where is_visible is currently used.
