Sorry, I just listed the AC97 stuff. In addition there is:
CONFIG_SND=y
CONFIG_SND_TIMER=y
CONFIG_SND_PCM=y
CONFIG_SND_JACK=y
CONFIG_SND_AC97_CODEC=y
CONFIG_SND_DRIVERS=y
CONFIG_SND_ARM=y
CONFIG_SND_PXA2XX_LIB=y
CONFIG_SND_PXA2XX_LIB_AC97=y
# CONFIG_SND_PXA2XX_AC97 is not set
CONFIG_SND_SOC=y
CONFIG_SND_SOC_AC97_BUS=y
CONFIG_SND_PXA2XX_SOC=y
CONFIG_SND_PXA2XX_SOC_AC97=y
CONFIG_SND_PXA2XX_SOC_COLIBRI270_V2=y
CONFIG_SND_SOC_I2C_AND_SPI=y
# CONFIG_SND_SOC_ALL_CODECS is not set
CONFIG_SND_SOC_WM9712=y
