Subject: [PATCH v8 00/11] PCI: imx6: Fix\rename\clean up and add lut
information for imx95
Fixed 8mp EP mode problem.
imx6 actaully for all imx chips (imx6*, imx7*, imx8*, imx9*). To avoid
confuse, rename all imx6_* to imx_*, IMX6_* to IMX_*. pci-imx6.c to
pci-imx.c to avoid confuse.
Using callback to reduce switch case for core reset and refclk.
Base on linux 6.11-rc1

- keep enable_ref_clk(), I will add more code to make disabe/enable symtric
- Link to v7: https://lore.kernel.org/r/20240708-pci2_upstream-v7-0-ac00b8174f89@nxp.com
Changes in v7:
- rework commit message for PCI: imx6: Fix i.MX8MP PCIe EP's occasional failure to trigger MSI
- Add Mani's review tags for patch 1, 5
- Fix errata number in commit message for patch 6
- replace set_ref_clk with enable_ref_clk in patch 4
- using regmap_set(clear)_bits in patch 4
- Use exactly the same logic with original code at patch 4

- Remove reduntant ':' at patch 9' subject.
- Change range to ranges for patch 10.
- Change error code to -ENODEV for patch 10.
- Link to v6: https://lore.kernel.org/r/20240617-pci2_upstream-v6-0-e0821238f997@nxp.com
Changes in v6:
- Base on Linux 6.10-rc1 by Bjorn's required.
- Remove imx95 LUT patch because it need more time to work out the
solution. This patch add 8qxp and 8qm and support and some bug fixes.
- Link to v5: https://lore.kernel.org/r/20240528-pci2_upstream-v5-0-750aa7edb8e2@nxp.com
Changes in v5:
- Rebase to linux-pci next. fix conflict with gpiod change
- Add rob and cornor's review tag
- Link to v4: https://lore.kernel.org/r/20240507-pci2_upstream-v4-0-e8c80d874057@nxp.com
Changes in v4:
- Improve comment message for patch 1 and 2.
- Rework commit message for patch 3 and add mani's review tag
- Remove file rename patch and update maintainer patch
- [PATCH v3 06/11] PCI: imx: Simplify switch-case logic by involve set_ref_clk callback
remove extra space.
keep original comments format (wrap at 80 column width)
update error message "'Failed to enable PCIe REFCLK'"
- PATCH v3 07/11] PCI: imx: Simplify switch-case logic by involve core_reset callback
keep exact the logic as original code

- Add patch about help function imx_pcie_match_device()
- Using bus device notify to update LUT information for imx95 to avoid
parse iommu-map and msi-map in driver code. Bus notify will better and
only update lut when device added.
- split patch call PHY interface function.
- Improve commit message for imx8q. remove local-address dts proptery. and
use standard "range" to convert cpu address to bus address.
- Check entry in cpu_fix function is too late. Check it at probe
