Add R-Car S4-8 (R-Car Gen4) PCIe controller for both host and endpoint modes.
To support them, modify PCIe DesignWare common codes.
Changes from v24:
https://lore.kernel.org/linux-pci/20231011071423.249458-1...
- Based on the latest pci.git / next branch.
- Reordering the patches. (This is suggested by Bjorn.)
- Drop "PCI: dwc: Disable two BARs to avoid unnecessary memory assignment"
because break other platforms.
- Modify the patch for the latest next branch in the patch 04/15.
- Add specific-setting by using dbi2 again in the patch 12/15.
- Modify commend of the specific-setting in the patch 12/15. Serge suggested
this on v23 but I missed to modify this on v24.
- Fix for -Wincompatible-function-pointer-types-strict int the patch 13/15.
Changes from v23:
https://lore.kernel.org/linux-pci/20230926122431.3974714-...
- Based on the latest pci.git / next branch.
- Remove Link tag and Krzysztof's s-o-b tags from all patches.
- Drop "PCI: dwc: Expose dw_pcie_write_dbi2() to module".
- Add "PCI: dwc: Disable two BARs to avoid unnecessary memory assignment".
- Add Reviewed-by in the patch 0[137]/16 and the patch 1[24]/16.
- Fix typo in the patch 14/16.
- Fix error messages and commit descriptions in the patch 1[234]/16.
- Change the subjects in the patch 1[34]/16.
- Use aplhabetical order on Kconfig in the patch 1[34]/16.
- Drop DWC spec code in the patch 13/16.
Changes from v22:
https://lore.kernel.org/linux-pci/20230925072130.3901087-...
- Based on the latest pci.git / next branch.
- Add Reviewed-by in the patch 12/16.
