[PATCH v2 0/7] PCI: intel-gw: Fixes to make the driver working again

[Florian Eckert]

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

* Move interrupt 'enable' to its own function to improve readability,
  and add additinal 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.
* Read ATU base assignment from the DTS rather than specifying it in the
  source of the driver.
* Remove unused preprocessor define.
* Mark driver as orphaned as the maitainer's email no longer works

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

[PATCH v2 1/7] PCI: intel-gw: Remove unused define

[Florian Eckert]

The C preprocessor define 'PCIE_APP_INTX_OFST' is not used in the sources
and can therefore be deleted.

[PATCH v2 2/7] PCI: intel-gw: Move interrupt enable to own function

[Florian Eckert]

To improve the readability of the code, move the interrupt enable
instructions to a separate function. That is already done for the disable
interrupt instruction.

In addtion, all pending interrupts are cleared and disabled, just as this
is done in the disable function 'intel_pcie_core_irq_disable()'. After
that, all relevant interrupts are enabled again. The 'PCIE_APP_IRNEN'
definition contains all the relevant interrupts that are of interest.

This change is also done in the Maxlinear SDK [1]. As I unfortunately
don’t have any documentation for this IP core, I suspect that the
intention is to set the IP core for interrupt handling to a specific
state. Perhaps the problem was that the IP core did not reinitialize the
interrupt register properly after a power cycle.

In my view, it can’t do any harm to switch the interrupt off and then on
again to set them to a specific state.

[PATCH v2 3/7] PCI: intel-gw: Enable clock before phy init

[Florian Eckert]

To ensure that the boot sequence is correct, the dwc pcie core clock must
be switched on before phy init call [1]. This changes are based on patched
kernel sources of the MaxLinear SDK.

[PATCH v2 4/7] PCI: intel-gw: Add start_link callback function

[Florian Eckert]

adds the missing callback function so that the driver works again and does
not abort with the following error messages during probing.

[PATCH v2 5/7] PCI: intel-gw: Remove atu base assignment

[Florian Eckert]

If no ATU resource is defined in the DTS, the default value is 0x300000[1].
This is set during probing in the function 'dw_pcie_get_resources()'[2].
The driver overwrites this again when its init callback is called in its
'intel_pcie_host_setup()' [3] function. This is because the value here is
'0xC0000' rather than '0x300000'. This callback is called by the dwc core
via 'pp->ops->init' [4].

function callstack:
intel_pcie_probe()
  dw_pcie_host_init()
    dw_pcie_host_get_resources()
      dw_pcie_get_resources() [2]
    pp->ops->init = intel_pcie_rc_init()
                      intel_pcie_host_setup() [3]

As backwards compatibility is not an issue here [5], the value for the ATU
resource is moved to the DTS and is therefore loaded by the dwc core. It
is therefore no longer necessary to overwrite the pci->atu_base address in
the init callback. The DTS must be modified so that the additional resource
is loaded correctly by the DWC core.

[PATCH v2 6/7] dt-bindings: PCI: intel,lgm-pcie: Make atu resource mandatory

[Florian Eckert]

The ATU information is already set in the dwc core if it is specified in
the DTS. The driver uses its own value here [1]. This information is
hardware specific and should therefore be maintained in the DTS rather
than in the source.

Backwards compatibility is not an issue here [5], as the driver is
exclusively used by Maxlinear.

reg = <0xd1000000 0x1000>,

What does that mean exactly? It is not used outside of Maxlinear
company, so it is purely internal device and no one outside of Maxlinear
has it?

Then we can as well remove it and I don't quite get why you are working
on this (since no one can use it outside of Maxlinear...).

Drop, irrelevant. You still break all users of this binding.

Background information:

The PCIe IP core is only available for Maxlinear’s URX851 and
URX850 SoCs. However, the chip was originally developed by Intel when
they acquired Lantiq’s home networking division in 2015 [1] for this
SoCs. In 2020 the home network division was sold to Maxlinear [2].

Since then, Maxlinear has been responsible for the driver. However,
their SDK is outdated and based on kernel 5.15. Other than that, not
much is happening! Even the developers listed as maintainers can no
longer be reached. When it came to the patch set, the email couldn't
be delivered  to the responsible developer
'Chuanhua Lei <lchuanhua@maxlinear.com>' either. The email bounced
back.

The company I work for is using the chip and is currently in the
process  of extracting the key components from the SDK so that the
SoC URX851/URX850 can work again with a mainline kernel again.

Maxlinear continues to sell that SoC. They are *not' EOL.
It’s just that their Board Support Package (SDK) is no longer
up to date.

As noted in link [3], a Maxlinear developer has stated that
backwards compatibility is not necessary here, as the IP core
is used exclusively by Maxlinear`s URX851 and URX850 SoC`s.

We use these SoCs in our Produkt for internet home gateway
routers.

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:
Lexical error: Documentation/devicetree/bindings/pci/intel-gw-pcie.example.dts:28.37-43 Unexpected 'config'

See https://patchwork.kernel.org/project/devicetree/patch/20260330-pcie-intel-gw-v2-6-8bd07367a298@dev.tdt.de

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

[PATCH v2 7/7] MAINTAINERS: Remove bouncing intel-gw maintainer
