You have description of entire property. The property consists of
phandles ("items", with only one item) and each phandle of two items
(second nested "items"). The first item in phandle is actual phandle, so
it does not need any constraints/schema, just a description. This was
missing.

Something like this:
https://elixir.bootlin.com/linux/v5.18-rc1/source/Documentation/devicetree/bindings/soc/samsung/exynos-usi.yaml#L42

except that in your case second item (in the nested items) have actual
schema, not description, which is good.



Best regards,
Krzysztof
