I think there was a reason for "sensors", because there can be other
bindings on the same level. Documentation/devicetree/bindings/hwmon/ltc2978.txt
lists "regulators", for example.

Where did you find the "sensors" example for ltc2978 ? I don't see it
in the upstream kernel. Or was that derived from the official "regulators"
bindings ?

Yes, I just followed the structure from there, renaming "regulators"
as "sensors".

Yes, let's do that. I'd like us to keep the "sensors" subnode to have a clear
association and differentiator to other sub-nodes such as "regulators".
Open is if we can use "temperature-sensor@0" or if it would have to be
a chip specific "ltd", but I think we can sort that out after suggesting
an initial set of bindings to Rob.

Makes sense, I'll do that. Now I just need to figure out how to
express that in YAML ...

I'll send a new patch as soon as I figured that out and got it to work.

Thanks for your input!

Oskar.
