JSON or YAML?

JAML is a superset of JSON. So it is not completely wrong. I've no idea if this particular binding sticks to the subset which is JSON. Andrew

I based that on other commits at that do something similar and say "Convert to JSON schema", although I might be operating on old data. Looking again now with `git log --oneline --no-merges --grep onvert -- Documentation/devicetree/bindings/` I see "Convert binding to YAML" and "convert to dtschema" (still a few json-schema in there). I guess technically the binding is written in YAML but forms part of schema which is ultimately consumed by jsonschema but perhaps the use of jsonschema is an implementation detail that doesn't require mentioning. I'm happy to reword the subject and send a v3 if people feel strongly about it.

Right now there is no way (that I have found) of dealing with non-PHY devices like the dsa switches so setting this to false generates warnings on turris-mox: arch/arm64/boot/dts/marvell/armada-3720-turris-mox.dtb: mdio@32004: Unevaluated properties are not allowed ('#address-cells', '#size-cells', 'ethernet-phy@1', 'switch0@10', 'switch0@2', 'switch1@11', 'switch1@2', 'switch2@12', 'switch2@2' were unexpected) From schema: /home/chrisp/src/linux/Documentation/devicetree/bindings/net/marvell,orion-mdio.yaml There are also warnings about the size of the reg property but these seem to be genuine problems that Marek is looking at.
