You would want to fix those IRQ_TYPE_NONE values as well because since
commit 83a86fbb5b56b5eed8a476cc3fe214077d7c4f49 ("irqchip/gic: Loudly
complain about the use of IRQ_TYPE_NONE") this is going to create some
nice warnings on boot.
I am about to send fixes for NSP and HR2 since that's what I have access
to at the moment, but it would be good if you could send updates to the
Cygnus and NS2 DTS files?
Thanks
