Can the "ASoC driver for TI DAVINCI EVM" support I2S Audio interface data transfer

Other Parts Discussed in Thread: OMAP-L138

 Hi,

I am using the OMAP-L138 Logic PD EVM and I'm trying to see if I can utilize I2S on the Audio interface.

In my experiment I reconfigured the AUDIO_FORMAT #define in ./sound/soc/davinci/davinci.evm.c to:

#define AUDIO_FORMAT (SND_SOC_DAIFMT_I2S | \
        SND_SOC_DAIFMT_CBS_CFS | SND_SOC_DAIFMT_NB_NF)

Now after doing this I expected to see the Audio interface timing characteristic to change from Figure 24 of the AIC3106 datasheet to Figure 23.

However the timing characteristics remains the same.

Now, I understand that it's the "ALSA SoC McASP Audio Layer for TI DAVINCI processor" module that configures the Audio data transfer.

Does this mean this module will only configure the audio interface for DSP mode?

I hope that this will be clarified.

 

Best Regards,

Grant
