Max Filippov 57b7068de5 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.

help
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
the drivers for the rest of XTFPGA audio subsystem.
