Hello, > According to Section 2.2 of the PCI Express Card Electromechanical > Specification (Revision 5.1), in order to ensure that the power and the > reference clock are stable, PERST# has to be deasserted after a delay of > 100 milliseconds (TPVPERL). Currently, it is being assumed that the power > is already stable, which is not necessarily true. Hence, change the delay > to PCIE_T_PVPERL_MS to guarantee that power and reference clock are stable. Applied to controller/j721e, thank you! [01/01] PCI: j721e: Deassert PERST# after a delay of PCIE_T_PVPERL_MS milliseconds https://git.kernel.org/pci/pci/c/22a9120479a4 Krzysztof
