Support the Synopsys DesignWare AHB DMA controller. This
can be integrated in chips such as the Atmel AT32ap7000.
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
platfroms that enumerate it as a PCI device. For example,
Intel Medfield has integrated this GPDMA controller.
config DW_DMAC_BIG_ENDIAN_IO
bool "Use big endian I/O register access"
default y if AVR32
depends on DW_DMAC_CORE
help
Say yes here to use big endian I/O access when reading and writing
to the DMA controller registers. This is needed on some platforms,
like the Atmel AVR32 architecture.
If unsure, use the default setting.
