5 bool "SuperH on-chip DMA controller (DMAC) support"
6 depends on CPU_SH3 || CPU_SH4
9 config SH_DMA_IRQ_MULTI
12 default y if CPU_SUBTYPE_SH7750 || CPU_SUBTYPE_SH7751 || \

20 bool "SuperH DMA API support"
23 SH_DMA_API always enabled DMA API of used SuperH.
24 If you want to use DMA ENGINE, you must not enable this.
25 Please enable DMA_ENGINE and SH_DMAE.
27 config NR_ONCHIP_DMA_CHANNELS
30 default "4" if CPU_SUBTYPE_SH7750 || CPU_SUBTYPE_SH7751 || \
31 CPU_SUBTYPE_SH7750S || CPU_SUBTYPE_SH7091

35 CPU_SUBTYPE_SH7785 || CPU_SUBTYPE_SH7724
38 This allows you to specify the number of channels that the on-chip
39 DMAC supports. This will be 4 for SH7750/SH7751/Sh7750S/SH7091 and 8 for the
40 SH7750R/SH7751R/SH7760, 12 for the SH7723/SH7780/SH7785/SH7724, default is 6.
43 bool "SH7760 DMABRG support"
44 depends on CPU_SUBTYPE_SH7760
46 The DMABRG does data transfers from main memory to Audio/USB units
48 Say Y if you want to use Audio/USB DMA on your SH7760 board.
51 tristate "PowerVR 2 DMAC support"
52 depends on SH_DREAMCAST && SH_DMA
54 Selecting this will enable support for the PVR2 DMA controller.
55 As this chains off of the on-chip DMAC, that must also be
58 This is primarily used by the pvr2fb framebuffer driver for
59 certain optimizations, but is not necessary for functionality.
64 tristate "G2 Bus DMA support"
65 depends on SH_DREAMCAST
68 This enables support for the DMA controller for the Dreamcast's
69 G2 bus. Drivers that want this will generally enable this on
