The max clock items for the dts node with compatible 'mediatek,mt8195-smi-sub-common' should be 3. However, the dtbs_check of such node will get following message, arch/arm64/boot/dts/mediatek/mt8195-evb.dtb: smi@14010000: clock-names: ['apb', 'smi', 'gals0'] is too long From schema: Documentation/devicetree/bindings/memory-controllers/mediatek,smi-common.yaml It's because the 'mediatek,mt8195-smi-sub-common' compatible incorrectly matches the 'else' conditions for gen2 HW without gals. Rewrite the 'else' condition to specifically identify the compatibles that utilizing gen2 HW without gals.
