Hello, This series is the continuation of previous work by Vidya Sagar [1] to fix the issues related to accessing DBI register space before completing the core initialization in some EP platforms like Tegra194/234 and Qcom SM8450. Since Vidya is busy, I took over the series based on his consent (off-list discussion). I've reworked the series in v7 to make it bisect friendly, and also to avoid build issue with the dependency. This resulted in the patches being heavily modified, so I took over the authorship of the patches. Testing ======= I've tested the series on Qcom SM8450 based dev board. I also expect it to work on Tegra platforms as well but it'd be good if Vidya or someone could test it. - Mani [1] https://lore.kernel.org/linux-pci/20221013175712.7539-1-vidyas@xxxxxxxxxx/ [2] https://lore.kernel.org/linux-pci/20230825123843.GD6005@thinkpad/ Changes in v7: - Rebased on top of v6.7-rc1 - Kept the current dw_pcie_ep_init_complete() API instead of renaming it to dw_pcie_ep_init_late(), since changing the name causes a slight ambiguity. - Splitted the change that moves pci_epc_init_notify() inside dw_pcie_ep_init_notify() to help bisecting and also to avoid build issue. - Added a new patch that moves pci_epc_init_notify() inside dw_pcie_ep_init_notify(). - Took over the authorship and dropped the previous Ack as the patches are heavily modified. Changes in v6: - Rebased on top of pci/next (6e2fca71e187) - removed ep_init_late() callback as it is no longer necessary For previous changelog, please refer [1].
