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. Since v1: - address one Vinod's comment - replace 5/6 & 6/6 by 5/5 from Rafael - tested on Intel Lynxpoint system Andy Shevchenko (4): 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 Rafael J.
