You are right, the supply of pcie2x1 comes from VCC3V3_SYS. But if we change supply of pcie2x1 to VCC3V3_SYS, it will cause pcie30phy to fail to initialize normally. The error is the same as the following: > phy phy-fe8c0000.phy.4: rockchip_p3phy_rk3568_init: lock > failed 0x6890000, check input refclk and power supply > phy phy-fe8c0000.phy.4: phy init failed --> -110 > rockchip-dw-pcie: probe of 3c0800000.pcie failed with error -110 If both vpcie3v3-supply of pcie2x1 and pcie3x2 use VCC3V3_PCIE like the vendor kernel, they can initialized normally.
