Hi,
I've updated the yaml and post it in the patch series v3[1].
But I still keep the vendor specific property mstar,irqs-map-range as I
mentioned in the last reply.
Please review it.

No, but I just want to keep the format same as arm,gic, and let the

Mediatek DTV SoCs contain multiple legacy interrupt controllers that routes
interrupts to the GIC. And all the mt58xx series SoCs have this controller,
hence the name of the driver and binding.
