Subject: [PATCH V13 0/6] PCI: Loongson pci improvements and quirks
Date: Sat, 30 Apr 2022 16:48:40 +0800 [thread overview]
Message-ID: <20220430084846.3127041-1-chenhuacai@loongson.cn> (raw)
This patchset improves Loongson PCI controller driver and resolves some
problems: LS2K/LS7A's PCI config space supports 1/2/4-bytes access, so
the first patch use pci_generic_config_read()/pci_generic_config_write()
for them; the second patch add ACPI init support which will be used by
LoongArch; the third patch improves the mrrs quirk for LS7A chipset; The
fourth patch add a new quirk for LS7A chipset to avoid poweroff/reboot
failure, and the fifth patch add a new quirk for LS7A chipset to fix the
multifunction devices' irq pin mappings.
V1 -> V2:
1, Rework the 4th patch;
2, Improve commit messages;
3, Remove the last patch since there is better solutions.
V2 -> V3:
1, Add more affected device ids for the 4th patch;
2, Improve commit messages to describe root causes.
V3 -> V4:
1, Rework the MRRS quirk patch;
2, Improve commit messages to describe root causes, again.
V4 -> V5:
1, Improve the MRRS quirk patch;
2, Change the order of 2nd and 3rd patch;
3, Improve commit messages to describe root causes, again.
V5 -> V6:
1, Rework the 1st patch;
2, Adjust the order of the series.
V6 -> V7:
1, Use correct pci config access operations;
2, Add ACPI init support for LoongArch;
3, Don't move to quirks.c since the driver has ACPI support;
4, Some other minor improvements.
V7 -> V8:
1, Use CFG1 method for LS2K/LS7A pci config.
V8 -> V9:
1, Use pci_controller_data for the first patch.
V9 -> V10:
1, Add a patch to avoid LS2K/LS7A access unexisting devices.
V10 -> V11:
1, Rebased on 5.16-rc4.
V11 -> V12:
1, Rebased on 5.17-rc5.
V12 -> V13:
1, Rebased on 5.18-rc2;
2, Some minor improvements (adopt Rob Herring's suggestions).
