[PATCH 0/6] dmaengine: add ACPI DMA helpers and use them in dw_dmac

[Andy Shevchenko]

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
