Hope that is ok While this is a fix that we should have, I'm not certain I see why this is urgent. A dt can already have: compatible = "arm,gic-400", "arm,cortex-a15-gic"; Which will work _today_, before this patch. If we need to treat the A15 GIC string differently, we'll have to ensure we support the GIC 400 string first.
