21 bool "SuperH DMA API support"
24 SH_DMA_API always enabled DMA API of used SuperH.
25 If you want to use DMA ENGINE, you must not enable this.
26 Please enable DMA_ENGINE and SH_DMAE.

36 CPU_SUBTYPE_SH7785 || CPU_SUBTYPE_SH7724
39 This allows you to specify the number of channels that the on-chip
40 DMAC supports. This will be 4 for SH7750/SH7751/Sh7750S/SH7091 and 8 for the
41 SH7750R/SH7751R/SH7760, 12 for the SH7723/SH7780/SH7785/SH7724, default is 6.
43 config NR_DMA_CHANNELS_BOOL
45 bool "Override default number of maximum DMA channels"
47 This allows you to forcibly update the maximum number of supported
48 DMA channels for a given board. If this is unset, this will default
49 to the number of channels that the on-chip DMAC has.
51 config NR_DMA_CHANNELS
52 int "Maximum number of DMA channels"
53 depends on SH_DMA && NR_DMA_CHANNELS_BOOL
54 default NR_ONCHIP_DMA_CHANNELS
56 This allows you to specify the maximum number of DMA channels to
57 support. Setting this to a higher value allows for cascading DMACs
58 with additional channels.
61 bool "SH7760 DMABRG support"
62 depends on CPU_SUBTYPE_SH7760
64 The DMABRG does data transfers from main memory to Audio/USB units
66 Say Y if you want to use Audio/USB DMA on your SH7760 board.
69 tristate "PowerVR 2 DMAC support"
70 depends on SH_DREAMCAST && SH_DMA
72 Selecting this will enable support for the PVR2 DMA controller.
73 As this chains off of the on-chip DMAC, that must also be
76 This is primarily used by the pvr2fb framebuffer driver for
77 certain optimizations, but is not necessary for functionality.
82 tristate "G2 Bus DMA support"
83 depends on SH_DREAMCAST
86 This enables support for the DMA controller for the Dreamcast's
87 G2 bus. Drivers that want this will generally enable this on
