It is based on "Enable rk356x PCIe controller" series of Peter Geis v9: https://patchwork.kernel.org/project/linux-rockchip/list/?series=636944 Compared to PCIeV2 which uses the Naneng combphy, PCIe v3 uses a dedicated PCI-phy. New in this version is that lane-map is no separate patch and moved from PCIe- to phy-driver. Peter has tested m2-slot too and so the bifurcation. The Phy-Patch is now changed to original author, but our changes are squashed in.
