Hi Baruch, I am not sure whether a Tested-by would be applicable here as its
a different platform, that is why I left it out.

Currently, the IPQ8074 DTS regarding QMP PCI PHY-s and PCI controllers is
incorrect, it was all based on v1 of the SoC which is not supported at all.
Gen3 QMP PHY support is currently missing for IPQ8074 and I am working on
upstreaming that and will fix up all of the PCI-related stuff in the
DTS after that.

So, I would prefer to keep those separate and let this series get
merged, especially
since the DTS part has already been merged.

Robert
