[PATCH V8 1/5] PCI/ASPM: introduce pci_aspm_init() and add to pci_init_capabilities()

I think these can go in drivers/pci/pci.h instead of the public
include/linux/pci.h.  There's no ASPM section in drivers/pci/pci.h
yet, but I think we should add one.

It looks like the following things from include/linux/pci-aspm.h could
be moved there as well, since they're only used by the PCI core:

  void pcie_aspm_init_link_state(struct pci_dev *pdev);
  void pcie_aspm_exit_link_state(struct pci_dev *pdev);
  void pcie_aspm_pm_state_change(struct pci_dev *pdev);
  void pcie_aspm_powersave_config_link(struct pci_dev *pdev);
  void pcie_aspm_create_sysfs_dev_files(struct pci_dev *pdev);
  void pcie_aspm_remove_sysfs_dev_files(struct pci_dev *pdev);

This would be a separate patch.

Sure, let me work on this.
