Somehow this error is not reproducible on my setup. I have upgraded both
Dtschema (2024.11) and and yamllint.

Anyway, could you please confirm if the below addition would be sufficient?

select:
  required:
    - compatible
  properties:
    compatible:
      contains:
        const: operating-points-v2-adreno
