These devices can be configured as either PCIe Endpoints or as PCIe Root Complex. This patch series shall provide a driver to initiate transactions using this DMA. Single platform driver shall handle both EndPoint and Root DMA transfers. Patch 1 enables Root DMA register translation and interrupts Patch 2 corrects styling errors seen with checkpatch Patch 3 adds PCIe driver for end points Patch 4 adds Platform driver which handles DMA transactions for both PCI end points and Root DMA Patch 5 describes device tree bindings for Root DMA Ravi Shankar Jonnalagadda (5): PCI:xilinx-nwl: Enable Root DMA PCI:xilinx-nwl: Correcting Styling checks dmaengine: zynqmp_ps_pcie: Adding PS PCIe DMA driver dmaengine: zynqmp_ps_pcie: Adding PS PCIe platform DMA driver devicetree: zynqmp_ps_pcie: Devicetree binding for Root DMA .../devicetree/bindings/dma/xilinx/ps-pcie-dma.txt | 67 + drivers/dma/Kconfig | 12 + drivers/dma/xilinx/Makefile | 2 + drivers/dma/xilinx/ps_pcie.h | 44 + drivers/dma/xilinx/ps_pcie_main.c | 200 ++ drivers/dma/xilinx/ps_pcie_platform.c | 3055 ++++++++++++++++++++ drivers/pci/host/pcie-xilinx-nwl.c | 23 +- include/linux/dma/ps_pcie_dma.h | 69 + 8 files changed, 3468 insertions(+), 4 deletions(-) create mode 100644 Documentation/devicetree/bindings/dma/xilinx/ps-pcie-dma.txt create mode 100644 drivers/dma/xilinx/ps_pcie.h create mode 100644 drivers/dma/xilinx/ps_pcie_main.c create mode 100644 drivers/dma/xilinx/ps_pcie_platform.c create mode 100644 include/linux/dma/ps_pcie_dma.h -- 2.7.4
