help
Say Y if you want to add support for audio SoC on an
at91sam9x5 based board that is using WM8731 codec.
-
-config SND_AT91_SOC_AFEB9260
- tristate "SoC Audio support for AFEB9260 board"
- depends on ARCH_AT91 && ATMEL_SSC && ARCH_AT91 && MACH_AFEB9260 && SND_ATMEL_SOC
- select SND_ATMEL_SOC_PDC
- select SND_ATMEL_SOC_SSC
- select SND_SOC_TLV320AIC23_I2C
- help
- Say Y here to support sound on AFEB9260 board.
