Changes v4 to v5: - Remove the export symbol set_sdma_channel_info(), use current->mm->pasid for instead. - Reorganize the code and fix some indentations. - "dma-can-stall" now is not a required option in dts-binding Changes v3 to v4: - dts-binding * filename changed to hisilicon,ascend-sdma.yaml * use common property "dma-channel-mask" * make a clearer description of property "pasid-num-bits" Changes v2 to v3: - Fix dts-binding error: * Use "hisilicon" as a unified vendor prefix. Changes v1 to v2: - Fix dts-binding error: * change "compatible" to two exact models: ascend310/ascend910. * add vendor prefix for customized channel-map property. * add $ref for customized channel-map property. * remove unnecessary label in example. - Logic change in probe function: * If iommu sva feature is disabled, probe will not lead to failure - Use common driver apis: dev_xxx() devm_xxx() Guo Mengqi (2): dmaengine: Add HiSilicon Ascend SDMA engine support dt-bindings: dma: HiSilicon: Add bindings for HiSilicon Ascend sdma .../bindings/dma/hisilicon,ascend-sdma.yaml | 73 ++ drivers/dma/Kconfig | 10 + drivers/dma/Makefile | 1 + drivers/dma/hisi-ascend-sdma.c | 788 ++++++++++++++++++ 4 files changed, 872 insertions(+) create mode 100644 Documentation/devicetree/bindings/dma/hisilicon,ascend-sdma.yaml create mode 100644 drivers/dma/hisi-ascend-sdma.c -- 2.17.1
