33 This allows you to specify the number of channels that the on-chip
34 DMAC supports. This will be 4 for SH7091/SH7750/SH7751 and 8 for the
37 config NR_DMA_CHANNELS_BOOL
39 bool "Override default number of maximum DMA channels"
41 This allows you to forcibly update the maximum number of supported
42 DMA channels for a given board. If this is unset, this will default
43 to the number of channels that the on-chip DMAC has.
45 config NR_DMA_CHANNELS
46 int "Maximum number of DMA channels"
47 depends on SH_DMA && NR_DMA_CHANNELS_BOOL
48 default NR_ONCHIP_DMA_CHANNELS
50 This allows you to specify the maximum number of DMA channels to
51 support. Setting this to a higher value allows for cascading DMACs
52 with additional channels.
55 bool "SH7760 DMABRG support"
56 depends on CPU_SUBTYPE_SH7760
58 The DMABRG does data transfers from main memory to Audio/USB units
60 Say Y if you want to use Audio/USB DMA on your SH7760 board.
63 tristate "PowerVR 2 DMAC support"
64 depends on SH_DREAMCAST && SH_DMA
66 Selecting this will enable support for the PVR2 DMA controller.
67 As this chains off of the on-chip DMAC, that must also be
70 This is primarily used by the pvr2fb framebuffer driver for
71 certain optimizations, but is not necessary for functionality.
76 tristate "G2 Bus DMA support"
77 depends on SH_DREAMCAST
80 This enables support for the DMA controller for the Dreamcast's
81 G2 bus. Drivers that want this will generally enable this on
