I know that it's ugly, but the problem is how to distinguish the

The only real difference I know of is the PCI interrupt mapping. The

Hi,
I think I found an issue in the OF interrupt parsing code, although I
have to admit that my device tree source doesn't really follow the
specification.
First some information about my target setup. I didn't specify an

This is an interrupt controller (it has an interrupt-controller
