The main reason why I did not like a revert, was because it would remove the nice feature where the bus is enumerated automatically on link up. I assumed that the plan was to add Link Up IRQ support in pwrctrl in the future. If that is not the case, and the plan is instead to eventually remove the existing Link Up IRQ support, then perhaps you could simply apply patches from: https://lore.kernel.org/linux-pci/20251111105100.869997-8-cassel@kernel.org/ Either the whole series or just patch 1 and 2, maintainer's choice :) Kind regards, Niklas _______________________________________________ Linux-rockchip mailing list Linux-rockchip@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-rockchip
