[PATCH v2 0/8] PCI: hisi: Cleanups

[PATCH v2 0/8] PCI: hisi: Cleanups

[Bjorn Helgaas]

  - Add local "dev" pointers to reduce repetition of things like
    "&pdev->dev".

  - Remove platform drvdata because it appears unused (we called
    platform_set_drvdata() but not platform_get_drvdata()).

  - Name private struct pointer consistently within driver.

  - Remove redundant struct members.

  - Use generic DesignWare accessors when possible.

  - Pass device-specific struct to internal functions for consistency.

  - Include register block base in PCIE_SYS_STATE4 address to simplify
    users.

Nothing here should change the behavior of the driver.

Changes from v1:
  I dropped the following patches because they were a lot of churn for
  questionable benefit:
    PCI: hisi: Rename APB accessors
    PCI: hisi: Rename config accessors
    PCI: hisi: Name private struct pointer "hisi" consistently
      (Instead of renaming *all* the pointers, I only renamed enough to
      make them consistent within this file.)
    PCI: hisi: Swap order of hisi_apb_writel() reg/val arguments

[PATCH v2 1/8] PCI: hisi: Add local struct device pointers

[Bjorn Helgaas]

Use a local "struct device *dev" for brevity and consistency with other
drivers.  No functional change intended.

[PATCH v2 2/8] PCI: hisi: Remove unused platform data

[Bjorn Helgaas]

The hisi driver never uses the platform drvdata pointer, so don't bother
setting it.  No functional change intended.

[PATCH v2 7/8] PCI: hisi: Pass device-specific struct to internal functions

[Bjorn Helgaas]

Only interfaces used from outside the driver, e.g., those called by the
DesignWare core, need to accept pointers to the generic struct pcie_port.
Internal interfaces can accept pointers to the device-specific struct,
which makes them more straightforward.  No functional change intended.
