Subject: [PATCH v2 00/13] PCI: Simplify PCIe port driver

Message-ID: <152062141493.77693.9630397416694091342.stgit@bhelgaas-glaptop.roam.corp.google.com> (raw)

This is an attempt to move a few things out of the port driver.

I added these new patches since v1:

  Merge pcieport_if.h into portdrv.h
    Merge pcieport_if.h and portdrv.h to reduce clutter

  Remove unnecessary "pcie_ports=auto" parameter
    This is the default setting anyway, so specifying the parameter doesn't
    do anything.

  Encapsulate pcie_ports_auto inside the port driver
    "pcie_ports_auto" was declared in linux/pci.h even though nobody
    outside the port driver used it.

  Rename and reverse sense of pcie_ports_auto
    "pcie_ports_auto" is connected with the "pcie_ports=native" parameter,
    so rename it to match.

Other changes since v1:
  - Rebase onto my pci/portdrv branch.
  - Rename pcie_resume_early() to pcie_pme_root_status_cleanup() as
    suggested by Rafael.
  - Add Rafael's Reviewed-by tags.

v1: https://lkml.kernel.org/r/152040297576.240786.1532465558381209070.stgit@bhelgaas-glaptop.roam.corp.google.com
