How many of these do we expect?

Assuming these represent more than one interrupt, could you please
bracket them individually? e.g.

	interrupts = <20 21>, <22 23>, <24 25>, <26 27>;

It makes it far clearer that it's a list of multi-cell elements rather
than a giant binary blob, and usually makes it easier to read a dts.

Thanks,
Mark.
