Agreed - v3 drops cix,irq-router from the binding completely. We plan to handle the interrupt gate as firmware/pre-Linux platform setup for v3, so the DMA node should not describe it. With the property gone, the CIX-specific conditional in allOf goes away as well, and the binding is back to the generic controller properties plus the CIX compatible. The corresponding driver changes are in my reply on the driver patch. Best regards, Jelly
