Subject: Connecting to "PCI command write" interrupt on 4xx platforms

Hi,

I need to connect to the "PCI command write" interrupt on a 440EPx platform. This is UIC0/int#5.

Where should I add this interrupt in the DT? To the PCI node? In this case it will collide with the 
PCI interrupts.

My application is a 440EPx on a PCI addon card. So the PCI node is disabled in the DT.

Is there a way to get an interrupt number for request_irq() without querying the DT?
