I tried is_visible but it looks like it won't be that neat to
implement as some attributes of this driver don't really pass
the channel index to the store()/show() but some other indexes.

The channel index is not the only means that can be used to determine
the channel index. Many drivers use the position in the attrs[] array
to determine the channel index. I don't see why this would not be
possible here.

Hmmm, that should simply work...I didn't mean not possible though.

If you are very against the dynamical group, I can drop it to
leave the sysfs node as it was.

And for the name nodes that I was talking about above, I will
add an sysfs store() function so non-DT users can set them,
and I also removed the confusing "unknown" default name.

The label attributes are RO. Please follow the ABI.

temp[1-*]_label Suggested temperature channel label.

Thanks a lot for the hint. I looked up the doc and feel that
this one probably fits my situation more:
    in[0-*]_label   Suggested voltage channel label.

Will follow it in my next version.

Thank you
