Platform P2972-0000 supports enabling endpoint mode for C5 controller. This patch series adds support for PCIe endpoint mode in both the driver as well as in DT. This patch series depends on the changes made for Synopsys DesignWare endpoint mode subsystem that are currently under review @ https://patchwork.kernel.org/project/linux-pci/list/?series=202211 which in turn depends on the patch made by Kishon @ https://patchwork.kernel.org/patch/10975123/ which is also under review.
