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
Okay. Thanks for letting me know. How do you want this to be done for
Cygnus and NS2?
I guess I should have the fix patches to DTS done and sent out first,
and then rebase this INTx patch series against the patches with the fix.
Does that make sense to you?
Thanks,
Ray
