The changes of clock part is here [1]. [1] https://patchwork.kernel.org/project/linux-arm-kernel/cover/1725525535-22924-1-git-send-email-hongxing.zhu@nxp.com/ - #3 and #4 patches clean i.MX PCIe driver by removing useless codes. Patch #3 depends on [2]. [2] https://patchwork.kernel.org/project/linux-arm-kernel/cover/1723534943-28499-1-git-send-email-hongxing.zhu@nxp.com/ - 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. 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.
