The `snps,dwmac.yaml` binding currently sets `maxItems: 3` for the `interrupts` and `interrupt-names` properties, but vendor bindings selecting `snps,dwmac.yaml` do not impose these limits. Define constraints for `interrupts` and `interrupt-names` properties in various DWMAC vendor bindings to ensure proper validation and consistency.
