Krzysztof,

unfortunately, the controller/rockchip branch currently doesn't build:

drivers/pci/controller/dwc/pcie-dw-rockchip.c: In function ‘rockchip_pcie_ep_sys_irq_thread’:
drivers/pci/controller/dwc/pcie-dw-rockchip.c:407:17: error: implicit declaration of function ‘dw_pcie_ep_linkdown’;
	did you mean ‘dw_pcie_ep_linkup’? [-Wimplicit-function-declaration]
  407 |                 dw_pcie_ep_linkdown(&pci->ep);
      |                 ^~~~~~~~~~~~~~~~~~~
      |                 dw_pcie_ep_linkup


Could you possibly include the commit:
3d2e425263e2 ("PCI: dwc: ep: Add a generic dw_pcie_ep_linkdown() API to handle Link Down event")
from the controller/dwc branch in the controller/rockchip as well,
or rebase the controller/rockchip branch on top of the controller/dwc branch,
or merge the controller/dwc branch to the controller/rockchip branch?



Additionally, since you picked up Mani's series which removes
dw_pcie_ep_init_notify() on the controller/dwc branch:
9eba2f70362f ("PCI: dwc: ep: Remove dw_pcie_ep_init_notify() wrapper")

You will need to pick up this patch as well:
https://lore.kernel.org/linux-pci/20240622132024.2927799-2-cassel@kernel.org/T/#u
Otherwise there will be a build error when merging the controller/dwc
and the controller/rockchip branch to for-next.
The patch that I sent out can be picked up to the controller/rockchip right
now (since the API that Mani is switching to already exists in Linus's tree).



May I ask why all the branches for the different DWC glue drivers are not
based on the controller/dwc branch?
They are obviously going to be tightly related.


Kind regards,
Niklas
