Patches 4-5 were imported from Manivannan's Hikey 970 tree: https://git.linaro.org/people/manivannan.sadhasivam/96b-common.git/commit/?h=hikey970_pcie&id=4917380ad023c62960aa0f876bd4f23cefc8729e It contains the original port made by Linaro. patches 6 to 12 contains several cleanups applied on the top of Manivann's work, in order to simplify the extra data that would be required at DT, and to ensure that the power regulator needed to enable the PCI support on Hikey970 will be enabled before trying to power it on, as otherwise, PCI resource allocation will fail. - patch 13 is here mostly as an example about what is needed in order for PCIe (and Ethernet) to start working on Hikey 970. It won't apply cleanly, as it depends on another patch series, adding the needed regulator drivers. I'll re-submit patch 13 after the pending stuff gets merged upstream.
