From: Frank Wunderlich <frank-w@public-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
v9: https://patchwork.kernel.org/project/linux-rockchip/list/...
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.
