From: Frank Wunderlich <frank-w@xxxxxxxxxxxxxxx> This series adds Rockchip PCIe V3 support found on rk3568 SOC. It is based on "Enable rk356x PCIe controller" series of Peter Geis v8: https://patchwork.kernel.org/project/linux-rockchip/list/?series=634925 Compared to PCIeV2 which uses the Naneng combphy, pciev3 uses a dedicated pci-phy. This Version is still an RFC/RFT because i cannot only test PCIe-slot on R2Pro as the other is a M.2 Key-E where i don't have any Hardware. last 3 Patches show a replacement for bifurcation setting to make it more useful for vendor-indepent lane-mapping.
