Not what I said to do... Let me spell it out: interrupts: minItems: 1 items: - description: major interrupt for rings - description: addditional interrupt for ring 19 - description: addditional interrupt for ring 4 - description: addditional interrupt for ring 5 if: properties: compatible: contains: enum: - mediatek,mt7986-wmac then: properties: interrupts: minItems: 4 else: properties: interrupts: maxItems: 1 If there are 4 interrupts then you should always have all 4. It's not some OS config. However, as an ABI, you might want to allow 1. If so, then the if/then should just have the 'maxItems: 1' restriction for the compatibles which only have 1 interrupt in the h/w. Rob

The mt7986 can support four interrupts to distribute the interrupts to different CPUs.
