Subject: [PATCH v7 0/9] PCI: mediatek: fixup find_port, enable_msi and add PM, module support
Date: Mon, 15 Oct 2018 13:44:38 +0800	[thread overview]
Message-ID: <1539582287-9171-1-git-send-email-honghui.zhang@mediatek.com> (raw)

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 v6:
 - Remove the pci_unmap_iospace when remove the device since the
   devm_pci_remap_iospace is an devm_ version.
 - Commit message changed for patch 2(Fix class type for MT7622 as PCI_CLASS_BRIDGE_PCI).
 - Capitilizing "MSI" and "PM" in the patch title.

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.
