Sorry, besides the interrupt cascade, our interrupt architecture is most like this one.
https://github.com/torvalds/linux/blob/master/Documentation/devicetree/bindings/interrupt-controller/marvell%2Ccp110-icu.yaml#L74-L98
and also others
https://github.com/torvalds/linux/blob/master/Documentation/devicetree/bindings/mmc/aspeed%2Csdhci.yaml#L83-L107
I don't understand you doubt it, and also we have proven in our internal Linux release.

Could you point out more information what you doubt? And I can provide more information.
