RK3588 has one PCIE3 x4 lanes, with one dedicated PCIE phy. This introduces the following needed nodes: - its0 and its1 sub-nodes of gic - pcie30_phy_grf node With the existing rk3588-pcie3-phy-grf compatible string. - pcie3x4 and pcie3x2 nodes The main nodes for the pcie controller. They share the same phy, thus only one of them can be enabled. - pcie30phy node It's the dedicated PCIE phy. The differences between upstream and downstream dts are: - The interrupt cells Upstream has two ppi partitions, thus requires #interrupt-cells = <4> to specify which partition is preferred. - The configuration space The downstream goes with an invalid range window, and modifies DesignWare driver to use that invalid range as configure space. Change the cursed method to use the proper "config" reg. - Reg names The downstream always has unnecessary "pcie-" prefix, while upstream DesignWare driver never checks such prefix.
