7 bool "SuperH on-chip DMA controller (DMAC) support"
11 config NR_ONCHIP_DMA_CHANNELS
13 int "Number of on-chip DMAC channels"
14 default "8" if CPU_SUBTYPE_SH7750R || CPU_SUBTYPE_SH7751R
15 default "12" if CPU_SUBTYPE_SH7780
18 This allows you to specify the number of channels that the on-chip
19 DMAC supports. This will be 4 for SH7750/SH7751 and 8 for the
22 config NR_DMA_CHANNELS_BOOL
24 bool "Override default number of maximum DMA channels"
26 This allows you to forcibly update the maximum number of supported
27 DMA channels for a given board. If this is unset, this will default
28 to the number of channels that the on-chip DMAC has.
30 config NR_DMA_CHANNELS
31 int "Maximum number of DMA channels"
32 depends on SH_DMA && NR_DMA_CHANNELS_BOOL
33 default NR_ONCHIP_DMA_CHANNELS
35 This allows you to specify the maximum number of DMA channels to
36 support. Setting this to a higher value allows for cascading DMACs
37 with additional channels.
40 bool "SH7760 DMABRG support"
41 depends on CPU_SUBTYPE_SH7760
43 The DMABRG does data transfers from main memory to Audio/USB units
45 Say Y if you want to use Audio/USB DMA on your SH7760 board.
