interrupt number assignment dts file help

[Ken Williams]

I am trying to configure a dts file for the pci subsystem of a MPC8540 based
system.

I am expecting (hoping) that the value specified in the interrupts property
(98 in this example)
will be used as the virtual interrupt number and that I can later do a
request_irq using that number.

kernel: 2.6.26.3

The board level configuration is:
 ADR29 connected to IDSEL
 using INTA# only
 The PCI interrupt is connected to external IRQ2

What I see is that inside irq_create_mapping, a call to irq_find_mapping
produces a null virq,
so irq_alloc_virt is called and comes back with x12.  Can I assign the
number to 98 (x62)
using the dts?  Any help would be greatly appreciated.

Thanks

Ken
