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. V3: * Re-ordered patches in the series to make the driver change as the last patch * Took care of Thierry's review comments V2: * Addressed Thierry & Bjorn's review comments * Added EP mode specific binding documentation to already existing binding documentation file * Removed patch that enables GPIO controller nodes explicitly as they are enabled already Vidya Sagar (5): soc/tegra: bpmp: Update ABI header dt-bindings: PCI: tegra: Add DT support for PCIe EP nodes in Tegra194 arm64: tegra: Add PCIe endpoint controllers nodes for Tegra194 arm64: tegra: Add support for PCIe endpoint mode in P2972-0000 platform PCI: tegra: Add support for PCIe endpoint mode in Tegra194 .../bindings/pci/nvidia,tegra194-pcie.txt | 125 ++- .../boot/dts/nvidia/tegra194-p2972-0000.dts | 18 + arch/arm64/boot/dts/nvidia/tegra194.dtsi | 99 +++ drivers/pci/controller/dwc/Kconfig | 30 +- drivers/pci/controller/dwc/pcie-tegra194.c | 770 +++++++++++++++++- include/soc/tegra/bpmp-abi.h | 10 +- 6 files changed, 1007 insertions(+), 45 deletions(-)
