Thanks! Will fix it in the next version. >> Signed-off-by: Macpaul Lin <macpaul.lin@mediatek.com> >> --- >> Documentation/devicetree/bindings/iommu/mediatek,iommu.yaml | 3 ++- >> 1 file changed, 2 insertions(+), 1 deletion(-) >> >> diff --git a/Documentation/devicetree/bindings/iommu/mediatek,iommu.yaml b/Documentation/devicetree/bindings/iommu/mediatek,iommu.yaml >> index ea6b0f5f24de..a00f1f0045b1 100644 >> --- a/Documentation/devicetree/bindings/iommu/mediatek,iommu.yaml >> +++ b/Documentation/devicetree/bindings/iommu/mediatek,iommu.yaml >> @@ -96,7 +96,8 @@ properties: >> maxItems: 1 >> >> interrupts: >> - maxItems: 1 >> + minItems: 1 >> + maxItems: 5 > > You need to add an items list here, and probably some per compatible > constraints. What are each of the itnerrupts for? > According to Friday Yang's comment, The IOMMU of MT8195 has 5 banks: 0/1/2/3/4. Each bank has a set of APB registers corresponding to the normal world, protected world 1/2/3, and secure world, respectively. Therefore, 5 interrupt numbers are needed. >> >> clocks: >> items: >> -- >> 2.45.2 >> Will try to fix it and add some description for MT8195. I think this patch could be split as a separated patch from the origin patch set. It'll take some time to refine the patch. Thanks Macpaul Lin

The infra-iommu node in mt8195.dtsi was triggering a CHECK_DTBS error due to an excessively long 'interrupts' property. The error message was: infra-iommu@10315000: interrupts: [[0, 795, 4, 0], [0, 796, 4, 0], [0, 797, 4, 0], [0, 798, 4, 0], [0, 799, 4, 0]] is too long To address this issue, add "minItems: 1" and "maxItems: 5" constraints to the 'interrupts' property in the DT binding schema. This change allows for flexibility in the number of interrupts for new SoCs Fixes: bca28426805d ("dt-bindings: iommu: mediatek: Convert IOMMU to DT schema") Signed-off-by: Macpaul Lin <macpaul.lin@mediatek.com> --- Documentation/devicetree/bindings/iommu/mediatek,iommu.yaml | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
