Hi Rob,

I ran into error "is not of type 'object'" with two dashes in the property
name.

Thanks for noticing. Adding something like below produces errors for the
pinctrl-single,gpio-range property name:

  pinctrl-single,gpio-range:
    description: Optional list of pin base, nr pins & gpio function
    $ref: /schemas/types.yaml#/definitions/phandle-array
    items:
      - items:
          - description: phandle of a gpio-range node
          - description: pin base
          - description: number of pins
          - description: gpio function

  pinctrl-single,gpio-range = <&range 0 3 0>;

The error is:

pinctrl-single.example.dtb: pinmux@4a100040: pinctrl-single,gpio-range:
[[1, 0, 3, 0]] is not of type 'object'

Changing the property name second dash to something else makes it go away.

This is with dtschema 2022.12. Any ideas?

Regards,

Tony
