menu "DMA support" config SH_DMA_API bool config SH_DMA bool "SuperH on-chip DMA controller (DMAC) support" depends on CPU_SH3 || CPU_SH4 select SH_DMA_API default n config NR_ONCHIP_DMA_CHANNELS int depends on SH_DMA default "6" if CPU_SUBTYPE_SH7720 || CPU_SUBTYPE_SH7721 default "8" if CPU_SUBTYPE_SH7750R || CPU_SUBTYPE_SH7751R default "12" if CPU_SUBTYPE_SH7780 default "4" help This allows you to specify the number of channels that the on-chip DMAC supports. This will be 4 for SH7750/SH7751 and 8 for the SH7750R/SH7751R. config NR_DMA_CHANNELS_BOOL depends on SH_DMA bool "Override default number of maximum DMA channels" help This allows you to forcibly update the maximum number of supported DMA channels for a given board. If this is unset, this will default to the number of channels that the on-chip DMAC has. config NR_DMA_CHANNELS int "Maximum number of DMA channels" depends on SH_DMA && NR_DMA_CHANNELS_BOOL default NR_ONCHIP_DMA_CHANNELS help This allows you to specify the maximum number of DMA channels to support. Setting this to a higher value allows for cascading DMACs with additional channels. config SH_DMABRG bool "SH7760 DMABRG support" depends on CPU_SUBTYPE_SH7760 help The DMABRG does data transfers from main memory to Audio/USB units of the SH7760. Say Y if you want to use Audio/USB DMA on your SH7760 board. endmenu
