applied to mips-next.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea. [ RFC1925, 2.3 ]
(again, sorry for seeing this patch late)

I think this compatible string is very generic and with that comes some
problems.
There is actually two different versions of this IP: one which has
support for controlling the interrupt of the PCI controller on some
SoCs (Danube, xRX100, xRX200). Other SoC variants (Falcon, Amazon-SE)
don't have that interrupt-controller as they don't have PCI support.
Also there is at least one clock input. I *assume* we need to describe
it but I am not sure (as this platform doesn't use the common clock
framework yet).
My version of this can be found here [0]. It's still sitting in my
tree because it has a dependency on an ICU patch in my tree which I
could not make work properly yet.
Best regards,
Martin
