There are six instances, one of which is for internal purposes only\nand the other five are general purpose.\n\nThe first two patches in the series add the BPMP support needed to power\nup/down the PCI link. Patch 3 contains the device tree bindings for the\nPCIe controller. Before adding the driver in patch 5, patch 4 introduces\nsome new common wait times for PCIe and unifies the way that drivers use\nthem. Finally, patch 6 adds DT nodes for the controllers found on the\nTegra264 SoC.\n\nNote that this cannot be applied for v7.1-rc1 because there's a build\ndependency that's going through the Tegra tree. If you'd like to merge\nthis, please let me know and I can provide a branch with the\ndependencies resolved.\n\nChanges in v4:\n- strip out dependencies that are going in through the ARM SoC tree\n- revert bindings to oneOf construct so that we don't produce new DTC\n warnings\n- Link to v3: https://patch.msgid.link/20260326135855.2795149-1-thierry.reding@kernel.org\n\nChanges in v3:\n- integrate PCI standard wait times patch into the series to maintain\n bisectability\n- fix review comments from Mikko\n- Link to v2: https://patch.msgid.link/20260320225443.2571920-1-thierry.reding@kernel.org\n\nChanges in v2:\n- fix an issue with sanity-checking disabled BARs\n- address review comments\n- Link to v1: https://patch.msgid.link/20260319160110.2131954-1-thierry.reding@kernel.org\n\nThanks,\nThierry\n\n---\nThierry Reding (4):\n dt-bindings: pci: Document the NVIDIA Tegra264 PCIe controller\n PCI: Use standard wait times for PCIe link monitoring\n PCI: tegra: Add Tegra264 support\n arm64: tegra: Add PCI controllers on Tegra264\n\n .../bindings/pci/nvidia,tegra264-pcie.yaml | 174 +++++++\n arch/arm64/boot/dts/nvidia/tegra264.dtsi | 248 ++++++++--\n drivers/pci/controller/Kconfig | 10 +-\n drivers/pci/controller/Makefile | 1 +\n .../controller/cadence/pcie-cadence-host-common.c | 6 +-\n .../pci/controller/cadence/pcie-cadence-lga-regs.h | 5 -\n drivers/pci/controller/mobiveil/pcie-mobiveil.c | 4 +-\n drivers/pci/controller/mobiveil/pcie-mobiveil.h | 5 -\n drivers/pci/controller/pci-aardvark.c | 7 +-\n drivers/pci/controller/pcie-tegra264.c | 527 +++++++++++++++++++++\n drivers/pci/controller/pcie-xilinx-nwl.c | 9 +-\n drivers/pci/controller/plda/pcie-starfive.c | 9 +-\n drivers/pci/pci.h | 2 +\n 13 files changed, 946 insertions(+), 61 deletions(-)\n---\nbase-commit: bfbb8533d7293235b71e4096cc0bc9a5c0c20b20\nchange-id: 20260402-tegra264-pcie-e30abe23da07\n\nBest regards,\n-- \nThierry Reding <treding@nvidia.com>" }
