I will move the 'allOf: block' to go before 'additionalPropertie' in next patches.

I thought it was defined this way to accommodate different SoCs.
I will remove the 'minItems'. Should the correct version look like the following?

allOf:
- $ref: /schemas/interrupt-controller.yaml#
- if:
properties:
compatible:
enum:
- realtek,rtd1319-intc-iso
then:
properties:
interrupts:
items:
- description: isolation irqs
- description: rtc irq
...
...

Thanks for your feedback.

James
