Bjorn Helgaas df5192d9bb PCI/ASPM: Enable only L0s and L1 for devicetree platforms ... f3ac2ff148 ("PCI/ASPM: Enable all ClockPM and ASPM states for devicetree platforms") enabled Clock Power Management and L1 PM Substates, but those features depend on CLKREQ# and possibly other device-specific configuration. We don't know whether CLKREQ# is supported, so we shouldn't blindly enable Clock PM and L1 PM Substates. Enable only ASPM L0s and L1, and only when both ends of the link advertise support for them.
