	  Say Y or M if you want to add support for codecs attached to the
	  I2S interface on XTFPGA daughter board. You will also need to select

ASoC: add xtensa xtfpga I2S interface and platform XTFPGA boards provides an audio subsystem that consists of TI CDCE706 clock synthesizer, I2S transmitter and TLV320AIC23 audio codec. I2S transmitter has MMIO-based interface that resembles that of the OpenCores I2S transmitter. I2S transmitter is always a master on I2S bus. There's no specialized audio DMA, sample data are transferred to I2S transmitter FIFO by CPU through memory-mapped queue interface.
