[RFC/RFT 0/6] RK3568 PCIe V3 support

[Frank Wunderlich]

From: Frank Wunderlich <frank-w at 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
v7: https://patchwork.kernel.org/project/linux-rockchip/cover/20220416110507.642398-1-pgwipeout@gmail.com/

Compared to PCIeV2 which uses the Naneng combphy, pciev3
uses a dedicated pci-phy.

Frank Wunderlich (6):
  dt-bindings: phy: rockchip: add pcie3 phy
  dt-bindings: soc: grf: add pcie30-{phy,pipe}-grf
  phy: rockchip: Support pcie v3
  PCI: rockchip-dwc: add pcie bifurcation
  arm64: dts: rockchip: rk3568: Add PCIe v3 nodes
  arm64: dts: rockchip: Add PCIe v3 nodes to BPI-R2-Pro
