Hi Dmitry, Krzysztof,

Ack, I will rework this patch in v2.

For the commit message, I will explain the reason first and then describe
the actual change.

For the overlay reference, I was referring to patch 3 in this same series,
but I agree the commit message should not justify the SoC dtsi change by
referring to a board overlay. I will make this patch stand on its own by
explaining that compatible = "pciclass,0604" is needed on the pcie0_port
node in kodiak.dtsi to allow the PCI subsystem to associate the DT node
with the PCI-to-PCI bridge device.

Thanks,
Rahul
