Using child nodes is a good idea. However, you are converting the node name into
the hwmon 'label' attribute which I can not accept. First, it is undocumented,
second, it effectively creates an undocumented property (if one wants to configure
the shunt resistor value, one has to configure a child node which is converted
into a label), and third, it violates the hwmon ABI ('input1' is not a "hint
about what this voltage channel is being used for").
Oh. I see the point here now. Then a child name could be just input[123],
and I will add a separate optional child property to indicate the label.
Exactly. "label" is quite widely used as property name, so that should be acceptable.
I am not sure about index; we'll see if Rob has any comments.
