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/ (local) [2] https://lore.kernel.org/imx/inzg46tc2fwsajxq4vzdyuiq7krzy6xtcg2mjaieninz7zsmgm@mtdjr4tuegpq/ (local) 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.
