7 bool "SuperH on-chip DMA controller (DMAC) support"
8 depends on CPU_SH3 || CPU_SH4
12 config NR_ONCHIP_DMA_CHANNELS
15 default "6" if CPU_SUBTYPE_SH7720 || CPU_SUBTYPE_SH7721
16 default "8" if CPU_SUBTYPE_SH7750R || CPU_SUBTYPE_SH7751R
17 default "12" if CPU_SUBTYPE_SH7780
20 This allows you to specify the number of channels that the on-chip
21 DMAC supports. This will be 4 for SH7750/SH7751 and 8 for the
24 config NR_DMA_CHANNELS_BOOL
26 bool "Override default number of maximum DMA channels"
28 This allows you to forcibly update the maximum number of supported
29 DMA channels for a given board. If this is unset, this will default
30 to the number of channels that the on-chip DMAC has.
32 config NR_DMA_CHANNELS
33 int "Maximum number of DMA channels"
34 depends on SH_DMA && NR_DMA_CHANNELS_BOOL
35 default NR_ONCHIP_DMA_CHANNELS
37 This allows you to specify the maximum number of DMA channels to
38 support. Setting this to a higher value allows for cascading DMACs
39 with additional channels.
42 bool "SH7760 DMABRG support"
43 depends on CPU_SUBTYPE_SH7760
45 The DMABRG does data transfers from main memory to Audio/USB units
47 Say Y if you want to use Audio/USB DMA on your SH7760 board.
