In order to populate the PHB msi_domain, use the "msi-parent"
attribute to lookup a corresponding irq domain. If found,
this is our MSI domain.

This gets plugged into the core PCI code.

Hi Marc,

Since the whole patch series based on the fact that non PCI type
buses will use MSI-like interrupts, would it be better if getting
this field settled during OF populating?

Are you're thinking of letting random platform devices automagically
gain an MSI domain as they are discovered by DT? I feel like you looking
at it the wrong way.

Note that DT discovery doesn't imply a particular bus, and non-PCI
doesn't mean bus-agnostic. MSI-like interrupts really are a bus
property, and I'd rather see you implementing support for your favourite
bus (and do the MSI domain matching there).

Thanks,

	M.
