[PATCH V5 0/2] DMA: update acpi_dma_get_range to return dma map regions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The patch series changed acpi_dma_get_range to return dma regions
as of_dma_get_range, so that dev->dma_range_map can be initialized
conveniently.

And acpi_arch_dma_setup for ARM64 is changed wih removing dma_base
and size from it's parameters.

Remove ARCH_HAS_PHYS_TO_DMA for LoongArch and use generic
phys_to_dma/dma_to_phys in include/linux/dma-direct.h.

V1 -> V2
- Removed dma_base and size from acpi_arch_dma_setup' parameters
- Add patch to remove ARCH_HAS_PHYS_TO_DMA for LoongArch

V2 -> V3
- Add kerneldoc for acpi_dma_get_range changing
- Remove redundant code in acpi_arch_dma_setup, and check map

V3 -> V4
- Change title to "Use acpi_arch_dma_setup() and remove ARCH_HAS_PHYS_TO_DMA"
- Use resource_size() to get size 

V4 -> V5
- Change commit log for patch: Support multiple dma windows with different offsets
- Remove a unnecessary blank line
- Fix a bug of acpi_dma_get_range
