The changes of clock part are here [1]. [1] https://lkml.org/lkml/2024/10/15/390 - #3 and #4 patches clean i.MX PCIe driver by removing useless codes. Patch #3 depends on dts changes. And the dts changes had been applied by Shawn, there is no dependecy now. - Make core reset and enable_ref_clk symmetric for i.MX PCIe driver by #5 and #6 patches. - Use dwc common suspend resume method, and enable i.MX8MQ, i.MX8Q and i.MX95 PCIe PM supports by #7 and #8 patches. v4 changes: It's my fault that I missing Manivanna in the reviewer list. I'm sorry about that. - Rebase to v6.12-rc3, and resolve the dtsi conflictions. Add Manivanna into reviewer list. v3 changes: - Update EP binding refer to comments provided by Krzysztof Kozlowski. Thanks. v2 changes: - Add the reasons why one more clock is added for i.MX95 PCIe in patch #1. - Add the "Reviewed-by: Frank Li " into patch #2, #4, #5, #6, #8 and #9.
