    Subject[PATCH v6 0/9] PCI: mediatek: fixup find_port, enable_msi and add pm, module support
    Date
    From: Honghui Zhang <honghui.zhang@mediatek.com>

    This patchset includes misc patchs:

    The patch 1 fixup the mtk_pcie_find_port logic which will cause system
    could not touch the EP's configuration space that connected to PCIe slot 1.

    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.
