NAK

None of these platforms have gpio interrupts or any other board
interrupt controllers which need to be initialized early? I don't think
DT conversions are complete enough to tell.

We could do something like this, but there only needs to be a single
match list of all controllers and function. We should consolidate the
irqchips to drivers/irqchip first though. I have that action from Connect...

DT conversions are complete enough to tell.

We could do something like this, but there only needs to be a single
match list of all controllers and function. We should consolidate the
irqchips to drivers/irqchip first though. I have that action from Connect...

Atleast SPEAr600 have GPIO interrupts.

That would be good.
I am updating DT support for SPEAr3xx, where i need to use VIC OF
support. So i would still like to get this patch going and you can consilidate
code at irqchips level later. What do you say?

Some DT enabled platforms may only have the gic or vic included in their
match list currently because other interrupt controllers aren't yet
converted to DT. I believe Exynos is one such example.

No. I don't think moving this into the gic and vic code just to move it
back out later is a good idea. Just looking at the diffstat, the net
number of lines removed is not very compelling either.
