The patch 2 fixup the class type for MT7622. The patch 6 fixup the enable msi logic, the operation to enable msi should be after system clock is enabled. Call mtk_pcie_enable_msi in mtk_pcie_startup_port_v2 since the clock was all enabled at that time. The patch 7 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. -Rebased on this patchset. The patch 9 add loadable kernel module support. [1] https://patchwork.kernel.org/patch/10479079 Change since v5: - A bit improvement of mtk_pcie_find_port suggest by Lorenzo. - Add fixup tags of fix enable MSI logic in patch 6. - Add Acked-by tags from Ryder. Change since v4: - Add patch 2 to fixup class type for MT7622. - Add patch 3 to remove the redundant dev->pm_domain check - Add patch 4 to covert to use pci_host_probe - Add patch 5 to re-arrange the function define, this is a prepare patch for fixup the enable_msi logic, no functional changed have been made by this one. - Add patch 8 to save the GIC IRQ in mtk_pcie_port as a prepare patch for tear down the irq when remove the kernel module. - Re-arrange the find_port flow suggest by Lorenzo to make the code parse easier for the patch 1. - Remove the .pm_support in mtk_pcie_soc in patch 7 since if system pm was not supported, then those pm callbacks will never be executed for MT7622. So the .pm_support is not needed. 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.
