Hi Paul,
It seems very strange to appear another soc model in one soc's devicetree,
and before submitting this patch I referred to some other irq drivers.
Similar
usage was found in irq-sunxi-nmi.c and irq-omap-intc.c, and the original
irq-ingenic.c was declare jz4770, jz4775, jz4780 in the same way. So I
followed
the same method to add the declare of jz4760/x1000/x1500, this may be a
little
better.

All these compatible strings point to the exact same behaviour. It was
already a mistake to have the three "ingenic,jz47[70,75,80]-intc" here;
there should have been only one, e.g. "ingenic,jz4770-intc" and the other
two SoCs using it as a fallback compatible.
I think you don't need to add these, and in your devicetree just use
"ingenic,jz4780-intc" as a fallback compatible.
Cheers,
