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.
