[PATCH v4 0/7] PCI: intel-gw: Fixes to make the driver working again

[Florian Eckert <fe@dev.tdt.de>]

This series fixes and improve the 'intel-gw' driver to work again with
the current dwc pcie framework. The following changes are:

* Move interrupt 'enable' to its own function to improve readability,
  and add additional register writes just as the Maxlinear kernel does in
  their SDK.
* Enable clock for the PHY before PHY init call.
* Add missing 'start_link' callback. That was added to the PCIe dwc
  framework.
* Move ATU base address assignment to the probe function and also add the
  the possibility to read it from the devicetree by dwc core.
* Update devicetree documentation for intel-gw-pcie.yaml
* Remove unused preprocessor define.
* Mark driver as orphaned as the maitainer's email no longer works

Changes in v4:
- Add 'atu' to the end of the resource definition to ensure backwords
  compatibility.
- Updated the commit description to explain why the MaxLinear SDK is used
  as a reference.
- Remove 'Rahul Tanwar <rtanwar@maxlinear.com>' out of the loop, as the email
  address is no longer valid and is being rejected.
- Link to v3: https://lore.kernel.org/r/20260401-pcie-intel-gw-v3-0-63b008c5b7b2@dev.tdt.de

Changes in v3:
- Update commit messages.
- Correct the sample code for dt bindings by adding the missing quotation
  marks. Add 'minItems: 3' to avoid ABI issues.
- Move driver atu base assignment to probe function and keep backward
  compatibility.
- Link to v2: https://lore.kernel.org/r/20260330-pcie-intel-gw-v2-0-8bd07367a298@dev.tdt.de

Changes in v2:
- Added additional information to the commit descriptions
- Add additional patch to mark driver as orphaned as the maintainer's
  email no longer works.
- Fix wrong error path for enable clock before phy init.
- Add new patch to update the devicetree documentation for the 'atu'
  resource
- Add additional recipients responsible for documenting the dervicetree
  bindings.
- Link to v1: https://lore.kernel.org/r/20260317-pcie-intel-gw-v1-0-7fe13726ad4f@dev.tdt.de
