Great, thanks! I've picked up patches 3 and 4 into the Tegra tree for v5.7. Thierry

Tegra194 has three (C0, C4 & C5) dual mode PCIe controllers that can operate either in root port mode or in end point mode but only in one mode at a time. 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 recently accepted. @ 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.
