This controller can program the peripheral configuration so we add additional parameters in dma_slave_config for configuring the peripherals like spi and i2c. Changes in v6: - Fix error reported by dt tool Changes in v5: - Add acked by Rob - Move qcom-gpi-dma.h header to include/linux/dma/ - rebase and test on v5.10-rc2 Changes in v3: - Update the i2c tre creation based on testing feedback Changes in v2: - Update the binding and drop qcom specific properties - Move peripheral configuration as a pointer - Move submit queue for transactions to issue_pending Vinod Koul (3): dt-bindings: dmaengine: Document qcom,gpi dma binding dmaengine: add peripheral configuration dmaengine: qcom: Add GPI dma driver .../devicetree/bindings/dma/qcom,gpi.yaml | 88 + drivers/dma/qcom/Kconfig | 12 + drivers/dma/qcom/Makefile | 1 + drivers/dma/qcom/gpi.c | 2303 +++++++++++++++++ include/dt-bindings/dma/qcom-gpi.h | 11 + include/linux/dma/qcom-gpi-dma.h | 83 + include/linux/dmaengine.h | 5 + 7 files changed, 2503 insertions(+) create mode 100644 Documentation/devicetree/bindings/dma/qcom,gpi.yaml create mode 100644 drivers/dma/qcom/gpi.c create mode 100644 include/dt-bindings/dma/qcom-gpi.h create mode 100644 include/linux/dma/qcom-gpi-dma.h
