I don't want to apply [PATCH v9 2/4] because it didn't build. I haven't seen an updated series that *does* build. And it probably doesn't make sense for me to apply the arch/arm64 changes anyway because they aren't really in the PCI purview. If you want me to apply something, post patches 1 and 3 by themselves with the trival updates I included. Those are really only PCI and should build without error. > > From a > > PCI perspective, I think I could apply patches 1 and 3 pretty easily > > by themselves. > > > > If/when you post these again, please incorporate the following > > incremental diff to clean up various whitespace and capitalization > > nits (these are spread across several of your patches). > > > > > > diff --git a/Documentation/devicetree/bindings/pci/kirin-pcie.txt b/Documentation/devicetree/bindings/pci/kirin-pcie.txt > > index 68ffa0fbcd73..20357d840af1 100644 > > --- a/Documentation/devicetree/bindings/pci/kirin-pcie.txt > > +++ b/Documentation/devicetree/bindings/pci/kirin-pcie.txt > > @@ -24,8 +24,8 @@ Example based on kirin960: > > > > pcie@f4000000 { > > compatible = "hisilicon,kirin-pcie";
