ASoC: davinci-evm: HDMI audio support for TDA998x trough McASP I2S bus
Add machine driver support for BeagleBone-Black HDMI audio. BBB has
NXP TDA998X HDMI transmitter connected to McASP port in I2S mode. The
44100 Hz sample-rate and it's multiples can not be accurately produced
on BBB. The only supported sample format is SNDRV_PCM_FORMAT_S32_LE.
The 8 least significant bits are ignored.
