As Srikanth mentioned, there's a series of MSI-related stuff from Yijing.
I recently put them on my pci/msi branch, and they overlap a bit with
what you're doing here.
So I'll drop these for now. Maybe there's a way you can accomplish what
you need by implementing pcibios_msi_controller(), which Yijing added?
Also note that "msi-controller" is already being used in device tree (see
Documentation/devicetree/bindings/interrupt-controller/marvell), so maybe
you can do the name.
