+  gpio-ranges: true

I am not sure I have a good handle on the yaml schema definitions but
"gpio-ranges" feels like it should be a list of ranges not a boolean.

Something like -

    gpio-ranges:
      maxItems: 1

feels more appropriate.

I see both the usages in gpio bindings and for other range properties so
maybe it's OK. I hope Rob or somebody more knowledgeable on this can
clarify the usage.

If you know how many (or a range) entries there are for gpio-ranges, 
then maxItems is good. If you don't, then 'gpio-ranges: true' is fine. 
That doesn't make the property a boolean, but just says the property can 
be present.

Makes sense. Thanks for the explanation.
