You have also previously cherry-picked: 3d2e425263e2 ("PCI: dwc: ep: Add a generic dw_pcie_ep_linkdown() API to handle Link Down event") (from the pci/controller/dwc branch) which we also depend on. Perhaps the smartest thing right now is to just recreate the pci/controller/rockchip branch, by: 1) reset the rockchip branch to v6.10-rc1 2) merge the pci/controller/dwc branch to the rockchip branch 3) merge the pci/endpoint branch to to the rockchip branch 4) pick all the patches that are currently on the pci/controller/rockchip 5) squash: 246afbe0f6fc ("PCI: dw-rockchip: Use pci_epc_init_notify() directly") into the commit that adds dw-rockchip endpoint mode support (9b2ba393b3a6 ("PCI: dw-rockchip: Add endpoint mode support")) 6) squash: https://lore.kernel.org/linux-pci/20240626191325.4074794-2-cassel@xxxxxxxxxx/ into the commit that adds dw-rockchip endpoint mode support (9b2ba393b3a6 ("PCI: dw-rockchip: Add endpoint mode support")) This way: - All commits will build as individual patches, so no build errors from the test robot (even when it builds a patch that is in the middle (e.g. 10/11)). - Even if futher commits are applied to pci/controller/dwc or pci/endpoint, we will not depend on any newly applied patches to these branches, so there will be no need to "re-merge" the branches to the rockchip branch. Kind regards, Niklas
