[PATCH v2 02/14] arm64: dts: rockchip: enable second PCIe controller on the Qnap-TS433

Sun Jul 21 10:37:11 PDT 2024


The TS433 uses both pcie controllers for sata and the 2nd network
interface. Set the needed data-lanes in the pcie3 phy and enable
the second pcie controller, as well as remove the bifurcation comment.
