It's not a trivial device if it has it's own docs. So don't add it to that list
(the point is to not have separate docs for devices that don't really have
any device tree data other than where they are.
Few more bits inline.

That needs more detail. I've read the driver and I am not sure what exactly
you mean! Why should a scale have a threshold?

Not sure why these are in hex.. Or why we care if they are 8 bits. If there is
a limit
on the possible values, perhaps mention it in the docs above.

One blank line at the end is neough.
