What's actually state of the TDM container format support in ASoC?
I see there is that set_tdm_slot callback in struct snd_soc_dai_ops
but only pxa-ssp.c is setting it currently.

Am I correct that DSP_x, I2S are not multichannel but should be
embedded into TDM if multichannel operation is wanted?

So should Peter's these two patches take this API into use?
