[PATCH 0/2] PCI: qcom: Add PCIe support for upcoming Hawi SoC
Posted by Matthew Leung 1 month ago 
This series adds PCIe support for the Qualcomm Hawi SoC. The Hawi
platform features two PCIe controllers: one capable of Gen3 x2 operation
and one capable of Gen4 x1 operation. The first patch adds the device
tree bindings documentation for the Hawi PCIe controller, and the second
patch adds driver support by enabling the Hawi compatible string in the
existing qcom PCIe driver.

This series depends on the following prerequisite series:
- [PATCH v3 0/7] clk: qcom: Add initial clock controllers for the
  upcoming Hawi SoC (Change-ID: 20260316-clk-hawi-1ad4cad36d6a:v3)
- [PATCH v4 0/2] interconnect: qcom: Add support for upcoming Hawi SoC
  (Change-ID: 20260311-icc-hawi-d6dc165f8935:v4)

These dependencies add necessary headers for running dt_binding_check
against the binding.

These apply cleanly to v7.1-rc1.  I suppose the dt_binding_check thing
is the only real dependency?  Is there anything we need to do to
enforce the dependency when these get merged upstream during the merge
window?

I don't know where any of these change-ids or patch-ids come from.

Yes, the dependencies are only needed for running dt_binding_check as
the example dts snippet would produce an error on the missing headers.
The patches should apply and build cleanly otherwise.

I thought this check could be a problem for merging so added the
dependencies for completeness. If the binding check isn't a concern, I
can drop the dependencies.

These were generated by b4 after adding the change-id metadata for the
dependencies.

They should refer to the change-ids of the respective patch series:
- https://lore.kernel.org/all/20260506-clk-hawi-v3-0-530b538679f1@oss.qualcomm.com/

No, the dependencies are needed. It is also an indication that we cannot merge
this PCIe binding change, until the dependent headers are merged to mainline.

dt_binding_check should not fail in linux-next or in mainline.
