bool "Use DMA driver based on dmaengine"
depends on DMA_SPRD
default y if DMA_SPRD
help

config SND_SOC_SPRD_AUDIO_BUFFER_USE_IRAM
bool "Use IRAM when sound playback"
help
Say Y if you want use IRAM replacment RAM when playback.
sometimes, use IRAM maybe reduce power consumption.
but, it will cause system more busy, becuase the buffer smaller.
config SND_SOC_SPRD_IRAM_BACKUP
bool "Backup IRAM when sound playback"
depends on SND_SOC_SPRD_AUDIO_BUFFER_USE_IRAM
help
Say Y if you want backup IRAM when playback. sometimes,
IRAM maybe shared with other modules,
then you need to open this.
config SND_SOC_SPRD_AUDIO_USE_AON_DMA
bool "Use AON DMA when sound playback"
depends on SND_SOC_SPRD_AUDIO_BUFFER_USE_IRAM && DMA_SPRD && SND_SOC_SPRD_AUDIO_DMA_ENGINE
help
Say Y if you want to use AON DMA when playback, sometimes,
AON DMA maybe reduce power consumption. But AON DMA can only
access IRAM, so we must depend on IRAM switch.
