There is a patch series which introduces ACPI DMA helpers in similar way like we have for DeviceTree.
In addition it applies this to the first user, namely dw_dmac driver.
Andy Shevchenko (6): dma: acpi-dma: introduce ACPI DMA helpers dmaengine: call acpi_dma_request_slave_channel as well dma: acpi-dma: parse CSRT to extract additional resources dw_dmac: add ACPI support ACPI / LPSS: return no error from register_device_clock in special cases ACPI / LPSS: add Lynxpoint DMA controller to the list
