ZynqMP devices have PCIe Bridge along with DMA in PS. 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 DMA driver functionality for both PCI end points and Root DMA Patch 4 describes device tree bindings for Root DMA Ravi Shankar Jonnalagadda (4): PCI:xilinx-nwl: Enable Root DMA PCI:xilinx-nwl: Correcting Styling checks PCI: ZYNQMP PS PCIe DMA driver: Adding support for DMA driver PCI: ZYNQMP PS PCIe DMA driver: 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/xilinx_ps_pcie.h | 43 + drivers/dma/xilinx/xilinx_ps_pcie_main.c | 200 ++ drivers/dma/xilinx/xilinx_ps_pcie_platform.c | 3059 ++++++++++++++++++++ drivers/pci/host/pcie-xilinx-nwl.c | 23 +- include/linux/dma/xilinx_ps_pcie_dma.h | 69 + 8 files changed, 3471 insertions(+), 4 deletions(-) create mode 100644 Documentation/devicetree/bindings/dma/xilinx/ps-pcie-dma.txt create mode 100644 drivers/dma/xilinx/xilinx_ps_pcie.h create mode 100644 drivers/dma/xilinx/xilinx_ps_pcie_main.c create mode 100644 drivers/dma/xilinx/xilinx_ps_pcie_platform.c create mode 100644 include/linux/dma/xilinx_ps_pcie_dma.h -- 2.1.1 -- To unsubscribe from this list: send the line "unsubscribe dmaengine" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
