config SH_DMA_API
depends on SH_DMA bool"SuperH DMA API support" default n
help
SH_DMA_API always enabled DMA API of used SuperH. If you want to use DMA ENGINE, you must not enable this.
Please enable DMA_ENGINE and SH_DMAE.

help This allows you to specify the number of channels that the on-chip
DMAC supports. This will be 4for SH7709/SH7750/SH7750S/SH7751/SH7091, 8for SH7750R/SH7751R/SH7760, and12for SH7723/SH7724/SH7780/SH7785. Default is 6.
config SH_DMABRG bool"SH7760 DMABRG support"
depends on CPU_SUBTYPE_SH7760
help
The DMABRG does data transfers from main memory to Audio/USB units
of the SH7760.
Say Y if you want to use Audio/USB DMA on your SH7760 board.
config PVR2_DMA
tristate "PowerVR 2 DMAC support"
depends on SH_DREAMCAST && SH_DMA
help
Selecting this will enable support for the PVR2 DMA controller.
As this chains off of the on-chip DMAC, that must also be
enabled by default.
This is primarily used by the pvr2fb framebuffer driver for
certain optimizations, but is not necessary for functionality.
If in doubt, say N.
config G2_DMA
tristate "G2 Bus DMA support"
depends on SH_DREAMCAST && SH_DMA_API
help This enables support for the DMA controller for the Dreamcast's
G2 bus. Drivers that want this will generally enable this on
their own.
