The second patch fixup the enable msi logical, the operation to enable msi should be after system clock is enabled. The function of mtk_pcie_startup_port_v2's define location is re-arranged to avoid mtk_pcie_enable_msi's forward declaration. And call mtk_pcie_enable_msi in mtk_pcie_startup_port_v2 since the clock was all enabled at that time. The third patch was rebased and refactor of the v4 patch[1], changes are: -Add PM support for MT7622. -Using mtk_pcie_enable_port to re-establish the link when resumed. -Rebase on the previous two patches. The fourth patch add loadable kernel module support. Some of those patches was already reviewed-by Ryder Lee , so I just add the Reviewed-by tags in those patches. [1] https://patchwork.kernel.org/patch/10479079 Change since v3: - Remove pm_runtime_XXX ops in suspend and resume callbacks in the third patch. - Rebase to 4.19-rc1. Change since v2: - Fix the list_for_each_entry_safe parameter error. - Add Ryder's Acked-by flag. Change since v1: - A bit of code refact of the first patch suggested by Andy Shevchenko, and commit message updated. - Using __maybe_unused. - Remove the redundant list_empty check of the fourth patch.
