Subject: [PATCH v8 0/5] Add i.MX943 PCIe supports
Date: Tue, 24 Mar 2026 10:30:31 +0800 [thread overview]
Message-ID: <20260324023036.784466-1-hongxing.zhu@nxp.com> (raw)
This patch-set adds i.MX943 PCIe supports on EVK board. Please pay
attention to that it relies on the patch-set[1], and the PCIe1 port on
the EVK board relies on the [2].
Both of them are included in the v7.0 kernel.
[1] https://lore.kernel.org/imx/176649331066.523506.9443864112044699350.b4-ty@kernel.org/
[2] https://lore.kernel.org/imx/inzg46tc2fwsajxq4vzdyuiq7krzy6xtcg2mjaieninz7zsmgm@mtdjr4tuegpq/
Changes in v8:
- Drop the redundant strings since they are compatible with i.MX95.
Changes in v7:
- Fix the checkpatch.pl warning in the first patch. Sorry for not
understanding the comments provided by Krzysztof in the v4 patch-set.
- Adjust the compatible strings in alphabetical order.
Changes in v6:
- Let i.MX94 and i.MX943 EP mode compatible strings fallback to i.MX95 EP
mode complatible string too.
- Add missing space after "=" in pcie0_ep node.
Changes in v5:
- Add Reviewed-by tag in first patch.
- Add i.MX94/i.MX943 compatible strings.
- Add "dma" irq for i.MX94/i.MX943 PCIe.
- Add 'fsl,max-link-speed = <3>;' back. Because that Link speed is decided
by pcie_link_speed[pci->max_link_speed]; Found it when one Gen3 NVME SSD is
used in the tests.
Changes in v4:
- Add missing space after comma or '='.
- Remove 'fsl,max-link-speed = <3>;' in dts, since it's not required anymore.
Changes in v3:
- Fix build warning in the dtbs_check.
Changes in v2:
- Refine the nodes sequence refer to Frank's comments.
- Rely on [3], and remove the duplacated codes mentioned by Sherry.
