Changes in v1: Address comments from Rob Herring and Bjorn Helgaas: - Drop st,limit-mrrs and st,max-payload-size from this patchset - Remove single reset and clocks binding names and misc yaml cleanups - Split RC/EP common bindings to a separate schema file - Use correct PCIE_T_PERST_CLK_US and PCIE_T_RRS_READY_MS defines - Use .remove instead of .remove_new - Fix bar reset sequence in EP driver - Use cleanup blocks for error handling - Cosmetic fixes Christian Bruel (5): dt-bindings: PCI: Add STM32MP25 PCIe root complex bindings PCI: stm32: Add PCIe host support for STM32MP25 dt-bindings: PCI: Add STM32MP25 PCIe endpoint bindings PCI: stm32: Add PCIe endpoint support for STM32MP25 MAINTAINERS: add entry for ST STM32MP25 PCIe drivers .../bindings/pci/st,stm32-pcie-common.yaml | 45 ++ .../bindings/pci/st,stm32-pcie-ep.yaml | 61 +++ .../bindings/pci/st,stm32-pcie-host.yaml | 99 ++++ MAINTAINERS | 7 + drivers/pci/controller/dwc/Kconfig | 24 + drivers/pci/controller/dwc/Makefile | 2 + drivers/pci/controller/dwc/pcie-stm32-ep.c | 445 ++++++++++++++++++ drivers/pci/controller/dwc/pcie-stm32.c | 402 ++++++++++++++++ drivers/pci/controller/dwc/pcie-stm32.h | 17 + 9 files changed, 1102 insertions(+) create mode 100644 Documentation/devicetree/bindings/pci/st,stm32-pcie-common.yaml create mode 100644 Documentation/devicetree/bindings/pci/st,stm32-pcie-ep.yaml create mode 100644 Documentation/devicetree/bindings/pci/st,stm32-pcie-host.yaml create mode 100644 drivers/pci/controller/dwc/pcie-stm32-ep.c create mode 100644 drivers/pci/controller/dwc/pcie-stm32.c create mode 100644 drivers/pci/controller/dwc/pcie-stm32.h
