Subject: How to specify data format if playback/capture were different ?

Hi Mark, and ALSA ML

Now, I'm creating ak4554 AD/DA.
My question is about data format.

If my understand is correct,
we can specify cpu/codec deivce data format by using

	snd_soc_dai_set_fmt(dai, SND_SOC_DAIFMT_xxx);

But, ak4554 case, data formats are
 playback : SND_SOC_DAIFMT_RIGHT_J
 capture  : SND_SOC_DAIFMT_LEFT_J
and, it can't exchange this data format.

CPU driver should set these information for ak4554 when playback/capture.

Then, how to specify these data format on ALSA SoC ?

Best regards
