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
