I've just posted a fix for this (and another bug just like it) as part of a series that depends on this series: https://lore.kernel.org/all/20220629141000.18111-1-johan+linaro@xxxxxxxxxx/ Not sure if you need to respin a v16 just for this but otherwise it could be folded in here. > + contains: > + enum: > + - qcom,pcie-msm8996 > + - qcom,pcie-sc7280 > + - qcom,pcie-sc8180x > + - qcom,pcie-sdm845 > + - qcom,pcie-sm8150 > + - qcom,pcie-sm8250 > + - qcom,pcie-sm8450-pcie0 > + - qcom,pcie-sm8450-pcie1 > + then: > + oneOf: > + - properties: > + interrupts: > + maxItems: 1 > + interrupt-names: > + items: > + - const: msi > + - properties: > + interrupts: > + minItems: 8 > + interrupt-names: > + items: > + - const: msi0 > + - const: msi1 > + - const: msi2 > + - const: msi3 > + - const: msi4 > + - const: msi5 > + - const: msi6 > + - const: msi7 > + else: > + properties: > + interrupts: > + maxItems: 1 > + interrupt-names: > + items: > + - const: msi > + > unevaluatedProperties: false > > examples: Johan
