The patch set add driver and device-tree bindings for a dma controller
on HiSilicon Ascend310/910 platform.
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()
