Subject: [RFC/RFT v2 00/11] RK3568 PCIe V3 support
From: Frank Wunderlich <frank-w@...lic-files.de>
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.
