Hi Mauri,

I've managed to dig out my old series for reworking the orion5x PCI/PCIe
support, to the point where the two drivers are completely independent.

Please have a look at
https://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git/log/?h=orion-pci-cleanup

to see if this helps you at all. I see now that your DNS-323 only supports
PCIe but not PCI, so maybe it's not all that helpful for your machine,
but it should help for converting the other ones that do use legacy
PCI and want to base DT support on top of this work.
