Your SoBs are odd... second patch has totally reversed path comparing to
this one. What do you want to express here?

phandle cannot be in milliohms... Anyway, use existing widely used
property: shunt-resistor-micro-ohms

Drop battery node, not needed for example.

It does not look like you tested the bindings, at least after quick
look. Please run `make dt_binding_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).
Maybe you need to update your dtschema and yamllint.
