# # DMA engine configuration for dw # config DW_DMAC_CORE tristate select DMA_ENGINE config DW_DMAC tristate "Synopsys DesignWare AHB DMA platform driver" select DW_DMAC_CORE help Support the Synopsys DesignWare AHB DMA controller. This can be integrated in chips such as the Intel Cherrytrail. config DW_DMAC_PCI tristate "Synopsys DesignWare AHB DMA PCI driver" depends on PCI select DW_DMAC_CORE help Support the Synopsys DesignWare AHB DMA controller on the platforms that enumerate it as a PCI device. For example, Intel Medfield has integrated this GPDMA controller.
