"uniform" is not a verb.  Maybe "Unify register accessors"?

Add parens for function names, e.g., "mobiveil_host_init()".  This
occurs several more times, including both subject lines and changelogs.

Capitalize acronyms in English text (subject lines, changelogs,
comments), e.g., s/irq/IRQ/

This should give a hint about the purpose of refactoring.  Sounds like
it's to make it easier to support both host and endpoint mode?

"Byte" and "Half-Word" do not need to be capitalized.  Also, the
changelog has a typo: "Half-Work" for "half-word".

>   PCI: mobiveil: make mobiveil_host_init can be used to re-init host

Here's another of the places that need parens after the function name.

The reader of these changelogs likely doesn't know what internal
identifiers like "A-011577" mean, but *does* want a hint about what
problem is being fixed and what platforms are affected.  So instead of
the "ls_pcie_g4:" prefix, use something like:

  PCI: mobiveil: Work around LX2160A r1.0 config access erratum
  PCI: mobiveil: Work around LX2160A r1.0 split completion erratum

and mention the erratum ID (A-011577) in the changelog.  If you can
include the actual erratum text in the changelog, that would be even
better.

s/ERRATA/errata/ in the changelogs.

>   arm64: dts: freescale: lx2160a: add pcie DT nodes

"PCIe"

>   arm64: defconfig: Enable CONFIG_PCI_LAYERSCAPE_GEN4

I already asked you once [1] to:

  please pay attention to the changelog conventions, e.g., capitalize the
  first word of the sentence ("Remove flag ...", "Correct PCI base address
  ...", etc), capitalize acronyms like "PCI" and "IRQ", use parentheses
  after function names, etc.  You can see the conventions by running "git
  log --oneline drivers/pci/controller".

For example, instead of this:

  PCI: mobiveil: add link up condition check

it should be this:

  PCI: mobiveil: Add link up condition check

Please wait at least a few days before posting a v5 in case there are
other comments.

Thanks for your patience and will fix them in v5.

This patch series is a mixture of fixes, refactoring and development
and to be frank it is a bit hard to review. Keeping in mind all
the review comments already received and that I expect you to integrate,
do you mind splitting it in logical series each one serving a specific
purpose (eg fixes, Layerscape support, etc.) ?

Let's start with posting and merging the fixes first.

Thank you very much.
