I do not understand what is the problem with it. Do you have a pointer where it is forbidden? At least Documentation/devicetree/bindings/interrupt-controller/interrupts.txt says nothing againt using it in such cases. > We could use > /delete-property/ interrupts > in the board files that needs multiple interrupt parents? > What is the advantage of using that more complex solution? I would then prefer to have the same with omap3 and omap4. If we do anything about interrupts in board file here, they will have multiple parents. Regards, Andreas

Usually interrupts are overwritten in the board file to specify a mux-dependent dedicated wakeup irq, so there is interrupts and interrupts-extended property which is not allowed. That has generated a lot of noise during dts changes if just a phandle involved has randomly changed. Avoid that mess by specifying interrupts-extended in the dtsi file.
